The game takes the story further, with over 12 different missions to complete and battles against villains like Whiplash and Titanium Man. The game features cinematics and the voices of actors from the movie, such as Robert Downey Jr. and Terrence Howard.
The gameplay involves fighting armies of soldiers, tanks, and helicopters with a range of upgradeable weapons, including missiles, micro-grenades, repulsive shots, EMP blasts, a flame thrower, and the powerful "Unibeam". The suit's propulsion and armor systems can also be upgraded, and special armors from the comics can be unlocked. Upgrades can be earned by completing missions.
