Iron Man 2

Players can play as either Iron Man or War Machine, each with their own unique style. While Iron Man is sleeker and relies much more on energy weapons, War Machine is outfitted with ballistic weaponry and tougher armour. Iron Man can choose from multiple suits of armour, including Marks II through VI. Players can customize upgrades and weaponry on the armour. Weapons can also be switched during gameplay.
