Seven guns from your own Counter-Strike 2 come to Conan Exiles, with their CS2 models, sounds and damage: Glock-18, USP-S, Desert Eagle, AK-47, M4A1-S, SSG 08 and AWP.
Craft them at the Blacksmith's Bench, next to the swords. Each costs what a Conan weapon costs:
Glock and USP-S: the iron broadsword's cost.
AK-47 and M4A1-S: the iron two-handed sword's cost.
SSG 08: the iron spear's cost.
Desert Eagle: the steel longsword's cost.
AWP: the steel two-handed greataxe's cost.
Iron Rounds are made from Iron Bars at the same bench.
Put a gun on your hotbar and select it: the camera goes to first person like in CS. Left mouse shoots, with recoil and muzzle flash, and Conan's punch is off. The gun reloads by itself when the clip runs out, and U reloads. On the AWP and SSG 08, right mouse zooms in.
Human NPCs in camps sometimes drop a gun.
Single player. Needs Conan Exiles and Counter-Strike 2 installed. The first start reads your CS2 guns (under a minute). Conan starts without BattlEye, so play Single Player.
