Think Left4Dead, but with an emphasis on melee combat and persistent progression between matches.
Pick your character, pick your weapons, go into a mission for 20-30 minutes, bash rat/chaos skulls, then claim your loot afterwards. Do this over and over again until you get bored.
Exemplary sound design and weapon feedback. Cues are distinct and recognizable, weapons have a incredibly satisfying weight to them too.

A great co-op game for you to play with 1-3 friends and just kill time/hang out. Still worth playing even if you don't have any friends to play with however.
Higher difficulties are predisposed to throw a bunch of unfair situations at you though, so they may not be for those who get easily frustrated at video games.
