Bladeball is a cancelled extreme sport game that was in development by Cat Mother around 2002, for PC and the original Xbox. It was inspired by the Rollerball movie and you could imagine it as a more “violent” version of soccer / football: two teams in an arena, trying to score their point by any means. The team was able to develop an early prototype, but it was not as fun to play as they imagined it to be and decided to cancel it, to work on another game (Dead Justice, which was also canned). Unfortunately only a few, tiny screenshots remain from this lost project: we tried upscaling them to have a better idea of how Bladeball could have looked like in 2002. You can find them in the gallery below.
