Left 4 Dead style gameplay except better, and I say this as someone who loved Left 4 Dead 1 so much that I would play by myself on expert (on xbox but didn't have money for xbox live) with a controller. If you are going for perfected orange tier weapons then you will tear your hair out but you only need white tier weapons with good base stats to beat the hardest mission so, it's a min-maxer's hell. The skill update turned 4 classes, which already were distinct classes, into 12, and made leveling up actually useful besides getting better weapons. Left 4 Dead had more of a story. Seriously.
Oh and there is a in game cosmetic store that requires real life cash in case that's a hard line for any of you.
I enjoy and recommend.
Min-max at your own risk.
