Black Hole Assault — About this game
Humanity’s expansion across the solar system meets an alien threat, and combat is settled through giant C.A.M. robots. Black Hole Assault centres on one-on-one fights in arenas based on planets and moons. Operation BHA supplies the main campaign, while other modes allow a more direct contest. Learn the reach of your robot’s strikes and defence before closing in, because a single bout is won through spacing and timing rather than a long sequence of platform stages.
