We hear that ALIEN BREED EVOLUTION (Episode 1) released today for Xbox Live Arcade is at 1200 Microsoft Points. This is an error beyond Team17’s control (that means Microsoft XBLA made the mistake apparently).

Team17 would like to state that the correct price is just 800 Microsoft Points and this will be rectified as soon as possible.

The listing on Xbox.com stipulates the correct price:
