AFter spending a couple hours playing it yesterday,.. and from what I can tell beating the campain on the restistance side, the game is pretty fun. It is pretty close to TF2, however I hated, HATED TF2 and couldn't get into it. This game I have enjoyed so far, even though it looks to be a short one like Homefront. I plan to play on the other side today, and we'll see how that goes.
Like others, I was kind of hoping for a Borderlands type game, but this is nothing like it.
