The MEAT (Massive Evisceration And Trauma) system designates 22 different contact points on each enemy that will react realistically to players’ attacks – for example, you can cut enemies in half vertically and horizontally, dismember them at the hand or shoulder, even shoot off their lower jaw without removing the head entirely. This level of realism – and ultraviolence – makes the combat incredibly impactful.

Whenever a player makes a long-range headshot, messy bomb kills, or any other skillful takedown of zeds (the game's zombie-like creatures) it puts every player into 'zed time." This slow downs time, turning everything black and white, except for gunfire, explosions and blood, all beautifully rendered. Not only does it make you feel powerful, but also serves as positive reinforcement, since going into "zed time" means you or your team is doing well.

KF2 boast a rare co-op experience with up to 6 players, which is not the norm for most games, making it a unique experience.
