Alien Challenge (World) — About this game

Alien Challenge (World) pits eight unusual fighters against one another in best-of-three bouts before the surviving contender faces Claus. Six attack strengths separate light, medium and heavy punches from the equivalent kicks, giving special-move inputs several possible finishes. Forward and backward double taps provide quick movement, and desperation techniques require a flashing life bar. Each character brings a distinct set of moves, so learning a reliable special and controlling distance are useful first steps toward the final opponent.
