Here's a trailer you have to watch, got me interested in the game even though its just a cgi trailer. pretty sweet teaser, Don't have much more info than its suppose to be a non-linear open world fps that works on mostly using melee weapons that you pick up. Anyway, check out the trailer, its awesome.
Maybe... but you know, actually good I can't say for sure, but it seems more open world, create hideouts and board em up, fend off the undead with some friends in multiplayer as well.
I doubt it. This game is going to be first person, set in an open world, and be up to four player co-op. Similarities, yes, but it would be like comparing Halo to Mass Effect.
Everything to you would be like L4D. IGN did a "rewind trailer" vid that's on their front page for this if you guys want to check it out.
