This is an interesting take on the action genre that plays out as a series of boss fights. Players take control of Ken (Kevin Striker in the Japanese version) and must destroy a main enemy in each combat arena before finding a portal and progressing to the next level. Ken is a fairly acrobatic guy, certainly by 8-bit standards, and can jump, wall grab, backflip, and even curve the short range projectiles fired from his extremities via punching and kicks.
