Great idea, well implemented.

when the game is a Tower Defense / Shooter mix. Man placed AA guns along several corridors to onrushing aliens to fight and kept away from the target point. The Ingenious: The defense guns are not enough but are quasi the support because the player himself is running in first-person shooter perspective through the corridors and fights the aliens. As far as I can tell so far, this mixture is very well done and it's great that Amazon for each controller purchase a promotional code here is causing buyers of the controller of this game get free. Too bad that some apparently had problems to find the field to redeem the voucher, however, do not understand why the game gives it only one star, which would be worth the full price for a minimum of four stars. I personally would prefer kept secret that I was overwhelmed to redeem with finding the placed on the home page directly under the "Buy Now" button link. ;-)
