not sure about that link because yuou need to be a member or their forum base to read that but i know you can play modded "game types" with a non modded xbox. Like this one sever i was in, they were playing a non modded zanzibar map and bullets acted as rockets with huge explosions except you didnt actually see them. Like if a guy was across the map from you, you could shoot half a clip of smg in the direction and then the other gy would feel a messed up rumble in the environment and would eventually kill him. I thought it was a pretty cool mod.
