We'll be making a fully featured new Iconic weapon in this guide, which is designed for first-timers and goes into details into every aspect about weapon modding. (not appearances)
Each Iconic weapon is a variant of a base weapon, with an hidden (from the player) mod.
This "hidden" mod contains a statModifiers array (to list all the stat changes this Iconic will have from the base weapon) and an OnAttach array.
The OnAttach array is where you'll want a GameplayLogicPackage to go. You may or may not need to define conditional effectors in there, but if you want your weapon to have the customary Iconic yellow description then be aware that there is where it's written (in the UIData of the GameplayLogicPackage).
Step 0: Understanding the structure
The rest of this guide will hold your hand through a deep dive, step-by-step, of your first custom Iconic made from zero. If you get lost through it, or if you'd rather find your own flow, you'll be well served by returning to check the code of an Iconic weapon already in the game (as you'll be building up from a base weapon in the same way, and it's solid footing).
RedMod tweak files are much more legible than a "TweakXL override" from WolvenKit for this, as each step there inherits redundant stuff passively and won't clutter your screen. Plus you'll see inlines content directly without having to track down flats.
Just use something to search the insides of the files for the definitions (VS can, or some free tools like Agent Ransack)
Step 1: Create a New Project in WolvenKit
Start by opening WolvenKit and create a new project. This will be the base for your new iconic weapon mod.
Step 2: Choose the weapon and create an override
Decide on the weapon you want to modify to make a new new iconic.
For this tutorial, we will use the gun 'Unity' as our base (Items.Preset_Unity_Default). If you want to use a different weapon, you can refer to Spawn Codes (BaseIDs/Hashes) or find a list of all in-game items here.
After locating the Unity gun in the tweak browser, right-click on the item and select "Add TweakXL Override". This allows you to modify and customize the weapon’s attributes to create your new iconic weapon.
To read more about Tweak modding, check TweakDB: Game database. This isn't necessary for understanding this guide!
Step 3: Editing and understanding your new tweak
Open the overridden tweak file in a code editor of your choice (such as Notepad++ or VS Code). You will be presented with a .yaml file containing roughly a million fields.
How does it work?
For first time modders, understanding all this in one go will be difficult. You can just keep these explanations handy and revisit them when required.
The .yaml file may seem complex at first glance, but the actual structure is extremely simple. Your weapon has properties – those stand on the left side of the :, such as ammo. The properties have different values, and those stand on the right side of the :, such as Ammo.RifleAmmo.

Step 4: Making a new weapon
4.1: New weapon, same as the old weapon
Making a new weapon is fairly simple. In your tweak file, change the Item ID in the very first line to "Items.Hand_Of_Midas" and save (Hotkey: Ctrl+S).
Items.Preset_Unity_Default:-> Remove thisItems.Hand_Of_Midas:-> Add this
That's it, you've created a new weapon now. This weapon will look & behave exactly like the Unity handgun, but trust me, it's new.
To test it out, boot up your game and load any save.
Type in the command below and hit Enter.
Game.AddToInventory("Items.Hand_Of_Midas",1)
You can now see your newly created weapon in your inventory.
Unfortunately, there is no way to tell it apart from the Unity handgun.
We'll get to fixing that, but first, a little cleanup: open up your WolvenKit & rename your overridden tweak file to "hand_of_midas.yaml". We will store all the edits that need to be done to our new weapon in this file.
4.2: Changing the carbon copy
Let's change something that will differentiate our weapon from the default Unity.
To do this, open your renamed tweak file & find the crosshair tag (hotkey: Ctrl+F). Replace it as shown below, and save your file.
crosshair:Crosshairs.Simple -> remove thiscrosshair:Crosshairs.Tech_Round -> add this
Now hot reload your game (Insert how to link here) or close it, reinstall your mod in WolvenKit & relaunch your game (From here on, this will be referred to as hot reload).
Spawn in both the Unity & Hand of Midas using the CET console:
You should now be able to see that both the Unity & Hand Of Midas, although otherwise identical, now have different crosshairs.
How did we figure out the crosshair ID?
How do we know that it's called "Crosshairs.Tech_Round" ?
Method 1: The REDmod DLC
If you have the REDmod DLC installed, you can use a text editor like Notepad++ to do a full-text search under Cyberpunk 2077/tools/REDmod. By searching for crosshair:, you can find all value assignments in the game files.
By searching for "Crosshairs." in the Tweak Browser. Most things we find inside the weapon tweak will be searchable within the Tweak Browser, and some within the Asset Browser.
Editing the Tweak will allow us to modify all of our gun's behaviors, and I encourage you to play around with these.
Step 5: Removing redundant code
We're only changing a single property in the Hand of Midas. For that, we have a tweak file with more than 200 lines of code. Can't we do this in a better way?
We can, and we should!
In later steps of this guide, you'll need to look up properties. Either keep a copy of your full tweak file (e.g. on your desktop), or refer to An annotated example above.
Using $base instead of $type
Items.Hand_Of_Midas:$base:Items.Preset_Unity_DefaultJust the properties we want to edit ...ORItems.Hand_Of_Midas:$type:gamedataWeaponItem_RecordAll the other properties ...
As shown above, when using $type to define a tweak, we need to add all the required properties for the type, but when using $base to define one, we only need to add the properties we are changing, the rest are taken from the parent.
Now go ahead and change it so we use a $base & only define the crosshair. Your entire tweak should now look like this:
What good is a new gun without a new name? We need to tell our game about these.
Open your WolvenKit project and navigate to the archive folder
Create a new folder named after your mod, for example midas_collection
Within this folder, make a subfolder named localization
How does the game assign display names?
In your full tweak file, search for the field called displayName. You'll likely encounter something like displayName: LocKey#49794.
This connects the displayName property of your item with a locaization key, which is the mechanism that the game uses to support multiple languages. Think of the LocKey of a list entry, with different lists being used for different languages.
So we edit onscreens.json?
Good thinking, but no. In Cyberpunk, only one mod can edit any given file. That is why ArchiveXL exists, and we'll use it to create a new translation entry for us.
Place a dedicated en-us.json file in your midas_collection\localization folder. This is where we'll add our own translation entries – after that, we only need to tell ArchiveXL about the file and lean back.
Setting up a localizationKey
Open the file in Wolvenkit and create a new entry in localizationPersistenceOnScreenEntry. It has the following properties:
Property name
your value
explanation
femaleVariant
Hand Of Midas
the default translationse
maleVariant
only set this if you want to show a different translation when your item is equipped by a person of the male body gender
primaryKey
0
The actual entry in the translation list, make sure to set this to 0 so that it's autogenerated
secondaryKey
MC_gun_name
The key used in tweak files to identify this translation string
secondaryKeys must be globally unique, or they will overwrite each other.
Create another entry with the secondaryKey of MC_gun_description and write a little fluff text for the description.
For more detailed guidance on these properties, check out the ArchiveXL Wiki.
Tell ArchiveXL about our new translation file.
In your WolvenKit project, go to the resources folder and create a plain text file with the following contents:
This localizedDescription: is not the yellow text you see on the weapon, but the red-colored description that is shown in the Inspect screen.
The text that is shown (as yellow-colored) on the weapon is instead defined in the UIData of the Iconic Mod (at Step 12)
These lines set the display name and the description of your weapon using the keys defined in your localization file. The values on the right side of the : must match the secondaryKey values from your en-us.json file and be globally unique.
After completing these steps, install your mod and launch the game. Your new weapon, "Hand Of Midas", should now appear with its unique name and description, fully integrated into Cyberpunk 2077's multi-language environment.
Step 7: Make it Iconic
To elevate the 'Hand of Midas' to its iconic status, we need to modify the .yaml again, where we set all of the gun's unique features:
# Hand of Midas weapon tweakItems.Hand_Of_Midas:$base:Items.Preset_Unity_Default# $base makes it so all the properties are taken from the specified tweak (in this case, "Items.Preset_Unity_Default") and the properties specified in this tweak overwrite the parent.crosshair:Crosshairs.Tech_Round# other crosshairs can be found by looking for "Crosshairs." in Tweak BrowserdisplayName:LocKey("MC_gun_name")# name of the gun (will be fetched from "LocKey#MC_gun_name" secondary key in "en-us.json")localizedDescription:LocKey("MC_gun_description")# description of the gun (can be seen when previewing the gun from inventory with "V" key)tags: - !append-onceIconicWeapon# prevent the gun from being dissassembledstatModifiers:# stats for a weapon - reload time/aim speed/magazine size/recoil kick/damage per second/etc. - !append-onceQuality.IconicItem# makes the weapon iconicstatModifierGroups:# stats for a weapon also, but grouped (generally by category) - !append-onceItems.IconicQualityRandomization
The new things you're seeing are arrays, which is a technical term — you can think of them as lists, since they can hold multiple items.
You can read more about how array operations work in TweakXL.
statModifiers will hold all the stats for your gun. from recoil to damage. Since the $base: Items.Preset_Unity_Default already defines statModifiers, and we'd like to keep those.
So we're adding an entry to the list, using!append-once followed by the new entry Quality.IconicItem.
This makes the weapon iconic, which means:
it has a fancy golden background
there's a dialogue box when you disassemble it
To prevent it from being disassembled, we also add IconicWeapon to its tags array.
Upgrade compatibility
We make sure that the weapon updates correctly by setting the
statModifierGroups:# stats for a weapon also, but grouped (generally by category) - !append-onceItems.IconicQualityRandomization
What exactly it does is somewhat of a mystery, so let me know if you find out.
Go test
Once these modifications are in place, install your mod and enjoy the newfound Iconic status of the 'Hand of Midas' in the game.
Technically, you've already made a new Iconic weapon & I should call quits on this tutorial, but it's never as easy as that, is it? Give yourself a pat on the back & onto the next step.
Step 8: Audio - Gun Go Boom
Let's talk theme.
The gun is called Hand Of Midas, so it would be fitting to have the gun sounds be more… gold-ish, right? How do we achieve this?
We could add custom sounds using RedMod, but due to how that works, we could end up with conflicts that we don't want to bother with. So let's look for guns that already have a sound like that.
Dex's gun Items.Preset_Liberty_Dex already has a nice metallic ring to it, so let's just steal its sound effect. To do this, find the gun in Tweak Browser and look for the property audioName.
Now add this value to your weapon tweak as shown below.
# Hand of Midas weapon tweakItems.Hand_Of_Midas:$base:Items.Preset_Unity_Default# $base makes it so all the properties are taken from the specified tweak (in this case, "Items.Preset_Unity_Default") and the properties specified in this tweak overwrite the parent.crosshair:Crosshairs.Tech_Round# other crosshairs can be found by looking for "Crosshairs." in Tweak Browsertags: - !append-onceIconicWeapon# prevent the gun from being dissassembleddisplayName:LocKey("MC_gun_name")# name of the gun (will be fetched from "LocKey#MC_gun_name" secondary key in "en-us.json")localizedDescription:LocKey("MC_gun_description")# description of the gun (can be seen when previewing the gun from inventory with "V" key)statModifiers:# stats for a weapon - reload time/aim speed/magazine size/recoil kick/damage per second/etc. - !append-onceQuality.IconicItem# makes the weapon iconicaudioName:wea_set_liberty_dex -> add thisstatModifierGroups:# stats for a weapon also, but grouped (generally by category) - !append-onceItems.IconicQualityRandomization
Install your mod and test it out, Hand Of Midas now sounds metallic like we intended it to.
Step 9: Weapon Design 101 - Conceptualization of your Iconic (Optional)
So now let's make it completely overpowered and take all fun out of using it!
Joking. Let's talk about how we can avoid that trap.
The 'Hand of Midas' is envisioned to be a unique piece with its own character - ideal for players who relish precision and skill. So we need strengths and limitations to give it a clear identity.
Here's how we achieve this:
Increased Recoil: This adds a layer of complexity and skill. High recoil means each shot requires careful consideration, appealing to players who enjoy a challenge and the satisfaction of mastering a weapon.
Smaller Magazine Size & Increased Reload Time: Every bullet counts. A smaller magazine encourages accuracy over spray-and-pray, and a longer reload time not only adds a strategic layer to combat but also gives players time to appreciate the weapon's aesthetics.
In summary, these design choices don't just balance the weapon; they enhance its identity. The "flaws" don't destroy the gun — instead, they contribute to making the 'Hand of Midas' feel powerful and rewarding for those who can wield it effectively.
Building on Strengths
Once the limitations are set, focus on the weapon's strengths to complement its defined character.
Increased Headshot Damage & Crit Chance: This change rewards accuracy and skill, making the weapon ideal for players who excel in precision shooting.
Increased Zoom on ADS & Extended Effective Range: Enhances the weapon's utility in long-range combat, aligning with its identity as a sharpshooter's choice.
To change the stats discussed in the step above, we again need to tinker with the statModifiers & statModifierGroups in your weapon tweak. Open up the tweak for Items.Preset_Unity_Default and navigate till you find the two arrays.
These arrays don't directly contain the stats, but have inline objects, which in turn will contain the actual stats. I recommend browsing to each of these stats in the Tweak Browser to find out what each one does. You can also read about Base Stats and what they do here.
You can add the code below to a new tweak (.yaml) file, or add it to your weapon's file.
To change the gun's recoil, we'll add a new statModifierGroup tweak as shown below
# Recoil related stats for Hand of MidasStatGroups.Hand_Of_Midas_Recoil_Stats:$type:gamedataStatModifierGroup_RecordstatModifiers: - $type:gamedataConstantStatModifier_Recordvalue:2modifierType:MultiplierstatType:BaseStats.RecoilTime# time taken by gun to reach the recoil distance - $type:gamedataConstantStatModifier_Recordvalue:1.5modifierType:MultiplierstatType:BaseStats.RecoilKickMin# minimum sway on camera/gun on shooting - $type:gamedataConstantStatModifier_Recordvalue:1.5modifierType:MultiplierstatType:BaseStats.RecoilKickMax# maximum sway on camera/gun on shooting - $type:gamedataConstantStatModifier_Recordvalue:1.5modifierType:MultiplierstatType:BaseStats.RecoilRecoveryTime# time taken to return to normal position after recoil
Now add this stat group to your weapon's tweak (see the last line).
# Hand of Midas weapon tweakItems.Hand_Of_Midas:$base:Items.Preset_Unity_Default# $base makes it so all the properties are taken from the specified tweak (in this case, "Items.Preset_Unity_Default") and the properties specified in this tweak overwrite the parent.crosshair:Crosshairs.Tech_Round# other crosshairs can be found by looking for "Crosshairs." in Tweak Browsertags: - !append-onceIconicWeapon# prevent the gun from being dissassembleddisplayName:LocKey("MC_gun_name")# name of the gun (will be fetched from "LocKey#MC_gun_name" secondary key in "en-us.json")localizedDescription:LocKey("MC_gun_description")# description of the gun (can be seen when previewing the gun from inventory with "V" key)statModifiers:# stats for a weapon - reload time/aim speed/magazine size/recoil kick/damage per second/etc. - !append-onceQuality.IconicItem# makes the weapon iconicaudioName:wea_set_liberty_dex# sets the sounds of Dex's gun - Plan BstatModifierGroups:# stats for a weapon also, but grouped (generally by category) - !append-onceItems.IconicQualityRandomization - !append-onceStatGroups.Hand_Of_Midas_Recoil_Stats -> add this
Install your mod, launch the game and test your changes. You should see that the gun's recoil is increased, but doesn't feel overwhelming.
You now know how to change your weapon's behavior. Play around & discover other stats and modify your gun to make it feel unique.
Stats can be added individually to statModifiers or in groups to statModifierGroups .
After a bit of tinkering, this is what my weapon tweak now looks like (expand the box below):

Step 11: Finishing up the Tweak
There are a lot of values to play around with in a tweak file. You are often better off leaving most of them alone. These are some properties you probably should look at when designing a gun.

Items.Hand_Of_Midas:...buyPrice:# multipliers to decide the buy price of the gun - Price.Hand_Of_Midas - Price.BuyPrice_StreetCred_DiscountsellPrice:# multipliers to decide the sell price of the gun - Price.Hand_Of_Midas - Price.WeaponSellMultiplier# Static price for Hand of MidasPrice.Hand_Of_Midas:$type:gamedataConstantStatModifier_Recordvalue:100000modifierType:AdditivestatType:BaseStats.Price
Step 12: Making an Iconic Mod (Special Ability)
The main thing that makes an iconic weapon so special is its iconic mod. These are like any other weapon mod, but hidden from the UI. Before you start hacking up your own, it is very important you have a look at the existing Iconic Mods in game.
For now, let's look at Items.Preset_Lexington_Wilson (also known as "Dying Night").
A big part of tweak modding is exploration — poking through tweaks until you find just the right thing to copy or change, or looking for something specific in hundreds of files.
Wilson's iconic iron
We'll end up with WilsonWeaponModAbility, which defines the abilities and stats that we care about.
Condition: Prereqs.ProcessHitTriggered - Does the bullet hit anything?
Effect: MultiplyDamageWithVelocity - Increases the guns damage with 25% if the Player velocity is greater than 10.
MultiplyDamage Effector
Condition: Perks.IsHitQuickMelee - Is the attack a Quick Melee attack?
Effect: MultiplyDamage - Increase damage by 50%
Adding an iconic mod
We have found an iconic mod in the mods_abilities.tweak for Wilson's gun, so now let's see that we apply this to the Hand of Midas.
Since our weapon demands perfection, we'll punish the player for not hitting headshots & reward them for hitting headshots. And because we want to make it hurt, we'll use HP reduction & Healing rewards.
You can add the tweaks below to your weapon's file or create a new tweak file.
Defining the ability
In this section, we first define our special ability Cranial_Cashback:
# Hand of Midas Iconic mod abilityItems.Cranial_Cashback:$base:Items.IconicWeaponModAbilityBase# effectors:# - !append-once Effectors.Punish_Miss# - !append-once Effectors.Heal_On_HeadshotUIData:$type:GameplayLogicPackageUIDatalocalizedDescription:LocKey("MC_gun_iconic_description")# iconic description shown in yellow text when hovering over a weapon
Add another entry (you can duplicate an existing entry)
Set the secondaryKey to the value in your tweak file, MC_gun_iconic_description
Set femaleVariant to your text — this will be showin on the tooltip in yellow.
. Make sure that it has the correct secondary key , and enter your fluff text as femaleVariant.
Defining the mod
Now that we have an ability, we need to register it as a mod:
# Hand of Midas Iconic modItems.Cranial_Cashback_Mod:$base:Items.IconicWeaponModBaseOnAttach: - Items.Cranial_Cashback
Adding the mod to the weapon
Now we can finally add the mod to the weapon by adding it to the slotPartListPreset:
# Hand of Midas weapon tweakItems.Hand_Of_Midas:# your other properties - cut out for readabilityslotPartListPreset:# attachments & mods - !append-once$type:SlotItemPartPresetitemPartPreset:Items.Cranial_Cashback_Mod# iconic modslot:AttachmentSlots.IconicWeaponModLegendary
Everything hangs together now, let's see if it works.
The full tweak
# Hand of Midas weapon tweakItems.Hand_Of_Midas:...slotPartListPreset:# attachments & mods - !append-once$type:SlotItemPartPresetitemPartPreset:Items.Cranial_Cashback_Mod# iconic modslot:AttachmentSlots.IconicWeaponModLegendary# Hand of Midas Iconic modItems.Cranial_Cashback_Mod:$base:Items.IconicWeaponModBaseOnAttach: - Items.Cranial_Cashback# Hand of Midas Iconic mod abilityItems.Cranial_Cashback:$base:Items.IconicWeaponModAbilityBase# effectors:# - !append-once Effectors.Punish_Miss# - !append-once Effectors.Heal_On_HeadshotUIData:$type:GameplayLogicPackageUIDatalocalizedDescription:LocKey("MC_gun_iconic_description")# iconic description shown in yellow text when hovering over a weapon
Go test
Install your mod — if your gun shows the yellow iconic description on hover, you're good to go.
If not, you may have to respawn it via CET.
Designing effectors
Now that we have The full tweak, we'll fill in the two effectors, one to punish the player for missing, and the other to reward them for headshots.
Heal on headshot
We'll heal for 80 HP every time the player pops somebody else's skull with the Hand of Midas. How do we do that?
The player's health is also a statPool item, it's called BaseStatPools.Health. We can copy this example and change it to meet our needs (for the final result, see The final effector):
However, the prerequisite for this effector is Items.MemoryReplenishmentEffector_inline0, which doesn't sound helpful.
We could now try to find an existing preReq that checks for headshots, but we can also write our own.
Creating a custom prereq
# Prereq to check if headshot & target is alive and hit with a ranged weaponPrereqs.Is_Target_Alive_And_Headshot:$type:gamedataHitPrereq_RecordcallbackType:HitTriggeredignoreSelfInflictedPressureWave:TrueisSynchronous:TruepipelineStage:ProcesspipelineType:DamageprereqClassName:HitTriggeredPrereq# how to refer to it later - Prereqs.HitTriggeredPrereqconditions: - Perks.IsHitTargetAlive_inline2# hit target is alive (health != 0) - Perks.HitIsBodyPartHead_inline0# headshot condition - Prereqs.Is_Attack_Ranged# condition to check if it's the bullet hitting the target and not a quick melee - Prereqs.Is_Weapon_Ranged# condition to check that the gun is source of damage and not a grenadeprocessMiss:False# process shots that hit npcs only
Now we have a custom preqrequisite, but we still have to fine-tune and link it:
Creating a custom condition
# Condition to check if attack type is rangedPrereqs.Is_Attack_Ranged:$type:gamedataHitPrereqCondition_Recordinvert:FalseonlyOncePerShot:Truetype:Prereqs.AttackTypeattackType:Ranged# Condition to check if weapon type is rangedPrereqs.Is_Weapon_Ranged:$type:gamedataHitPrereqCondition_Recordinvert:FalseonlyOncePerShot:Truetype:Prereqs.WeaponTypeweaponType:Ranged
Conditions are at the heart of a prerequisite, and here we have four.
Perks.IsHitTargetAlive_inline2 -> We don't want headshots on deadbodies to heal the player
Perks.HitIsBodyPartHead_inline0 -> Actual condition to check for headshots
Prereqs.Is_Attack_Ranged -> (Custom) We don't want quick melee attacks to heal
Prereqs.Is_Weapon_Ranged -> (Custom) We don't want grenades to be counted for this check.
The final effector
Now let's change our effector to use this prerequisite.
# Effector to heal player if they hit a headshotEffectors.Heal_On_Headshot:$type:ModifyStatPoolValueEffectorprereqRecord:Prereqs.Is_Target_Alive_And_HeadshotusePercent:FalsestatPoolUpdates: - $type:StatPoolUpdatestatPoolType:BaseStatPools.HealthstatPoolValue:80
Instead of punishing the player for just missing headshots, we can make our job easier by removing the HP every time they shoot, and compensating for the reduction in HP when hitting headshots by increasing our heal. Here's how we can do that:
# Effector to inflict damage on player when they shootEffectors.Punish_Miss:$type:ModifyStatPoolValueEffectorprereqRecord:Prereqs.Has_Player_ShotusePercent:FalsestatPoolUpdates: - $type:StatPoolUpdatestatPoolType:BaseStatPools.HealthstatPoolValue:-20# Prereq to check if the player has shot (bug - currently detects if a player has hit anything, not if shot)Prereqs.Has_Player_Shot:$type:gamedataHitPrereq_RecordcallbackType:HitTriggeredignoreSelfInflictedPressureWave:TrueisSynchronous:TruepipelineStage:PreProcesspipelineType:AllprereqClassName:HitOrMissTriggeredPrereqprocessMiss:True# process shots that miss npcsconditions: - Prereqs.Is_Attack_Ranged# condition to check if it's the bullet hitting the target and not a quick melee - Prereqs.Is_Weapon_Ranged# condition to check that the gun is source of damage and not a grenade
We've done a lot so far, so I'll leave all our changes here:
