It looks like Microsoft has finally
released the co-op patch for
Kameo: Elements of Power as well as a few new skin packs for the game. The co-op patch is free but the two sets will set you back 200 points each. I just checked my Xbox Live profile and it looks like they've added a few new Xbox Live Achievements to go along with the co-op mode but a quick glance and the Xbox forums indicates that there are no more achievement points to be had for acquiring them.
