it's just a simple "find-the-thing" game, but it does have a lot of easy achievements, which is great for completionists, 8/10

the best zombie game ever, it's great with friends, and the mods are just as abundant as garry's mod, 9.5/10

the best game to screw around in, you can have so many fun experiences in this game, and pretty much the entirety of steam has it, 10/10
