My only complain is that shoulder weapon button is in a place that makes it dificult to use. It should be at the "end" button, for example, or the game offer a keymap option. 4/5 for that.
1/5 because I don't like this things like "pay for play". I'd surelly donate some money for it because it has the potencial to be good, but now, it's like Swords and Sandals piece of crap.
