If you want face paced action stay away from this game. It's tedious and quite boring.
If you're looking to have some fun blasting enemies away left and right like their game-play trailer, forget about it. It's nothing like that at all. You'll spend most of your time fighting the controls and boredom. ...not even worth a rental to the casual action adrenaline junkie gamer. If you've got 6 days - 6 weeks to waste on learning to master this game, perhaps it would be worth it for you, for everyone else save your money.
