When it comes to weapons in Killing Floor 3, they are essential to how you deal with different enemy types. Every Zed has specific resistances and weaknesses, so it helps you to plan your loadout instead of just grabbing whatever you find.
The game lets you buy weapons and tweak them with different damage types, which becomes more critical as the waves get tougher. With that in mind, here is a guide on getting and customizing Weapons in Killing Floor 3.
Where to find Weapons in Killing Floor 3
You can get the Weapons through the Trader Pod between waves. After you clear a wave, you’ll have a short window ( about 90 seconds ) to visit the Trader and purchase guns, tools, ammo, or upgrades. This is also where you can equip attachments to shift damage types if you need to prepare for upcoming enemies.
You can even buy cheaper weapon variants at the start of the match. Having one of these ready early on can help you deal with basic enemies without waiting several waves to afford a better gun.
How Weapon Customization Works in Killing Floor 3
Weapon customization is handled at the Armory located in Nightfall’s base of operations, not at the Trader. You can either walk up to the Armory terminal or access it quickly using the shortcut menu (press Tab on PC). Once inside, the process is straightforward:
- Choose the weapon you want to modify.
- Create a new custom loadout slot.
- Select an empty mod slot and craft an attachment.
- Equip the attachment and save your loadout for future matches.
This lets you prepare multiple variants of the same weapon, which is helpful when building setups for different enemy types.

Building Weapons for Different Enemy Types
A balanced approach is to craft two main setups — one for common Zeds and another for armored threats. Each group has different weaknesses, so switching between the two can make a noticeable difference during harder waves.
Against Fleshy Enemies
- Recommended Damage Types: Heat, Biological, or Cut.
- Example: A rifle like Custom X295 Wraith 2 with Incendiary Rounds to burn through weaker Zeds. I’d recommend keeping attachments minimal at the start, as it reduces cost, so you can buy them early in the match.
Against Armored Enemies
- Recommended Damage Types: Soundwave, Acidic, or Force.
- Example: A weapon like Custom SCAR EIR with Overpressured Rounds combining Force and Soundwave damage works well against bosses with heavy armor.

Customizing Weapons for Your Playstyle
Each class can take advantage of different weapon mods. For instance, the Ninja class can make good use of an Electrified Blade, combining Cut and Electrical damage, which stuns enemies and adds extra safety during close combat. Other classes may prefer ranged options with damage types that stack status effects like bleed or burn.
A good strategy is to keep an inexpensive version of each weapon early on and slowly upgrade with more attachments as you earn Dosh. This way, you have coverage for all enemy types without overspending at the start.
