Play Ironman X-O Manowar in Heavy Metal (USA, Europe) Online

Ironman X-O Manowar in Heavy Metal came out on the Game Boy in 1996, published by Acclaim Entertainment. It was part of that wave of licensed games that tried to mash up different comic book heroes, and it stood out just for being so strange. You don't see many games where you control two characters from completely different universes, especially on a handheld.

You alternate between Iron Man and X-O Manowar, each with their own set of levels and enemies. Iron Man flies and shoots repulsors at robots, while X-O Manowar moves on foot, using his sword to cut down alien foes. The goal is straightforward: fight through side-scrolling stages, defeat bosses, and clear the mission. The action is simple but demanding, with enemy patterns that require quick reactions. It feels like a solid, no-nonsense brawler from that era, and switching between the two heroes keeps the action from getting stale.
