4 version 1.1, a recently updated mod for 4, replaces the game's protagonist Niko with super hero Iron Man.
Apart from flying, the mod features different Iron Man armors, the ability to call for backup and flying enemies. It also includes Iron Man's range of weapons, such as minigun, shoulder darts, mini rockets, hand repulsor beam, chest repulsor beam and super cannon.
The latest update for the mod consists of improved flight animations, taking damage results in sparks flaring from the armor and players will now take damage if they crash into objects.
