Yeah but dat's WHFB not 40K, it wouldn't really work wiv 40k and if you make it work it wouldn't be much different to the original BB.
40k football the ball is a servo skull. Lol but once upon a time I thought of modding a game to be like a 40k basketball but everyone is jump troops there are two guards who don't fly but can shoot ( shoota boys, guardsmen, guardians, heretics ) and special units that grant special abilities like storm nob gives boma boys. But yea I like bludd bowl
