Killerball

Killerball is a videogame about a futuristic sports game published by Microïds in 1989 which blends American football with roller-skating, similar to the 1975 film Rollerball. This violent game is played in a circular rink where each 5-man team tries to score by putting the ball into the hole of the opposing team. Taking the ball from an opponent can only be done by knocking him down.
