So I finished: -gameplay is influenced by the new games aka: you can't carry loads of stuff anymore, health regen, very straight to the point (run there, press that button that we lit up for you, kill waves of monster, repeat) -The guns pretty much stayed the same with some few added ones. -the references are still awesome It was fun playing it but for me it was to short and some things like bosses can only be hurt by explosives etc were just terrible. The rare occasions that I would die were because I tried going another way then they wanted to, and I don't know about the multiplayer but I guess that they tried making that more interesting.
