"Artificial Stupidity: Meat Sims are the easiest AI enemies you can play against in multiplayer. They wander around drunkenly, ignoring weapons (and oftentimes you), and can barely hit the room they're standing in."

"If you play a custom game against Meat Sims with at least one of the ... weapon choices being explosive, then that team will have a negative score from all the suicides and team kills."
