Killing Floor 3 recently received a new update that added an additional Perk (class system) called the Gunslinger. Fatal Focus pulls out two auto-aiming pistols much like Titanfall, and it's Smart Pistol. You'll likely either build into a Glass Cannon Build or a Survivalist Build. For this particular build, you'll be lowering your health and focusing on increasing the overall damage output you can do to Zed. This co-op FPS isn't going to go easy on you, and you'll need to come very prepared to come out on top.
