Good shooter with excellent skill adaptive AI. Only 3 weapons though and short but not bad for 20 bucks.
It is short but for the price, it isn't that short. There are only 3 weapons but each as two firing modes. The AI is awesome though. If you die a couple times at a certain part, you'll go through and find a few less enemies or all the enemies you kill will drop health. I really like this option in a game because it takes away the frustration and you can always turn up the difficulty and the AI adjustment difficulty.
If you like FPSs, its worth a buy. Oh, and for the guys, this game has the best boob bobbing I've seen in a game to date. Very realistic. LOL!
