I saw the trailer before on an ad, but I wasn't really sure what to think of it. I still don't know what to think of it.
They have not released much info on it, I assume its going to be a Solo/Multiplayer action game much like borderlands only in a different setting, theme and plot. Defending the world(s) from a mechanical menace bent on devouring everything. Just what I could pick up from the teaser.
Something that plays similar to Left 4 Dead 2. Like 5 people fighting through mechanical alien things to get to a finish. I think it's like that.
