The game has one redeeming quality, and that's a completely out of place narrator that says things like "Double kill!" and "10 headshots!" to remind you that you're doing a good job. Thanks guy!
I started the game with high hopes, but in the hour or so that I played, the game just got more generic as I went, and by the end there was nothing motivating me to keep playing. So if you're looking for a game with some good shooting and don't need any fancy dialog or new mechanics, then pick up Alien Rage tomorrow! Otherwise, hang on to your $US20 for now.
Alien Rage comes out tomorrow, September 24th for Xbox Live Arcade, Playstation Network, and Steam.
