Left 4 Dead 2
There isn’t much that needs to be said about Left 4 Dead 2 at this point in time. It’s still one of the most popular multiplayer games on Steam, enjoys a healthy mod scene, and is a triumphant sequel that built on the already impeccable foundation of its inimitable predecessor. By now, it should just be software that’s already downloaded onto freshly delivered PCs and consoles. Left 4 Dead 2 is quite literally $1 right now, so quit playing around and get it already.
