Left 4 Dead 2
Now students, what do we do with zombies? That is correct, we shoot them in their horrible, rotting faces. Left 4 Dead 2 is pretty much the high water mark for zombie shoot ‘em ups, and it’s easy to see why: it’s got atmosphere, it’s got tension, and it’s a damn blast to play.
The introduction of new “infected” types really put Left 4 Dead 2 over the top. “Jockeys” will try to leap on players’ backs and try to steer them into zombie hordes, and “spitters” have a nasty ranged acid attack.
The ability to easily hop into and out of multiplayer co-op matches is the icing on the cake – and if someone does quit mid-match, their character will immediately be taken over by an AI that may or may not have eaten paint chips for breakfast.
