15 Games That Provided Hours of Fun at a Constant Clip

Left 4 Dead 2

Point gun at the zombie’s head, shoot, repeat x 1000. Add friends for even more enjoyment. Yes, there’s much more to Left 4 Dead 2 than that, from the varying objectives and different weapon types to tactics for handling Special Infected. However, the co-op shooter is also perfect for just zoning out, even solo, and annihilating hordes of zombies. The sheer amount of content and replay value, thanks to the AI Director, also doesn’t hurt.
