For example, the "Sharpshooter" perk, which provides accuracy benefits when using scoped rifles, can be raised in level by completing a number of headshots with specific weapons. Players can level up each perk to increase the benefits it offers. The perk, similar to the idea of a character class, provides bonuses towards certain weapon types, armor, movement, and other factors. Players select one of seven perks at the start of a match and between rounds. In Endless mode, you must survive unlimited hordes of zombies. In Human Survival mode, the gameplayer is similar to Killing Floor mode, except instead of zombies, you fight waves of Mercenaries. Players are encouraged to work together they can trade items and drop money, healing is more effective on other players than on oneself, and the team can strategically weld doors shut to provide a temporary barrier from the oncoming horde while funneling the other creatures to specific areas. Weapons can also be found randomly across the level. The trader buys and sells ammo, armor, and weapons, such as katanas, pipe bombs, flamethrowers and shotguns.

In Objective mode players complete different challenges while earning in-game money, which they can spend between waves at a trader. In Killing Floor mode, the player fights waves of zombie-like specimens - or ZEDs - with each wave becoming successively more difficult, until it concludes with a battle against a "boss" specimen called the Patriarch. Killing Floor 3 is a third-person shooter with four game modes: Killing Floor, Human Survival, Endless and Objective.
