Payday: The Heist is a great cooperative first-person shooter that might have slipped under your radar. The game was released back in October of 2011 with little fanfare, which is a shame as the game has a lot to offer.
In Payday, players can join up with three friends to form a group of four criminals who carry out some pretty intense robberies and heists. Payday includes a number of classic first-person shooter staples, but also has some pretty neat original mechanics. Each heist has multiple stages of objectives, meaning that you need to complete more than one simple objective to finish the heist. Working together will be familiar for people who have played other four-player cooperative shooters like Treyarch's popular Zombies mode in Call of Duty or Valve Software's Left 4 Dead franchise.
