@dsammy04: I think it's enjoyable both solo and co-op. But if you are playing with friends you should totally rise the difficulty or it becomes ridiculously easy.
@speed45823: Didn't you noticed he pointed at your comment and he didn't even mention this game?
Still, I think I found where the problem was for you: Let's have a look at your comments: "I uninstalled the game after just one session. My friends did the same."
So you only played one session of a beta, and you already decided that It's "a boring, generic and repetitive game"
I invite you and your friends to install and try the game again; that was the game's main menu. Yes; I agree it's uninspired and generic, but makes sure this time play what's after it. You may even like it :)
