Saw friends play it last night and I was very underwhelmed by it. The graphics had a neat cell-shaded style which is refreshing compared to the generic GRITTY graphics we've seen in just about FPS for the last 3 years. I don't really get what was so fun about it, sure you level up or whatever, but it's still your very standard FPS.
Maybe actually playing it would change my mind about the game, but I really doubt that :/
