PAYDAY2 is a pretty sweet 4-player co-op game where you rob banks, casinos, warehouses, car showrooms and break your buddies out of police custody. It's a beast of a game that we've been playing for a few years.
There was a LOT of DLC released for it. And it's now (almost) all of it is available in one package for £14.23. It's GREAT value. The only bit that's missing is one character model that was left out because profits went to the H3H3 legal fund a few years ago.
We still play it at LANs and online - If you don't have it already this is a great chance to get the game and all the DLC for a bargain basement price.
