Iron Man X-O Manowar in Heavy Metal — About this game
Choose Iron Man or X-O Manowar before each mission, then fight through research facilities and city routes with jumping, flight and energy attacks. The lower energy meter refills when left unused, so rest between bursts of flight or chest fire. Their damage meters work in opposite directions: Iron Man fears an empty gauge, while X-O risks overload when his fills. Use checkpoints and passwords to continue the campaign. Read the mission briefing and choose a hero with Left/Right and START. Use A to jump, tap Up in the air to fly and release energy use to let the lower gauge recharge. Press Up near an object to pick it up, B to throw it, and note the next password at a checkpoint.
