Holosseum (US, Rev A) — About this game
Holosseum (US, Rev A) gives four fighters a small arena for best-of-three martial-arts contests. Weak and strong attacks share a two-button layout, while directional motions provide the individual techniques. The restricted space makes the distance to an opponent especially useful when choosing a quick strike or preparing a stronger move. In the single-player sequence, the selected fighter faces the other characters and then a mirror match before further random encounters. Learning one reliable motion provides a practical way into that compact fight.
