The player controls a robot spanning 42 feet or 13 metres in a series of 16 missions consisting of destroying certain enemies and buildings. Some missions require the player to obtain new weapons from an enemy base or destroy other robots.

The player has a wide variety of weapons like rocket launchers, a chainsaw, gatling gun, shield, and self-controlled rockets, which can be equipped on any part of the robot.

The gaming media reported that Iron Soldier would support two-player gaming via the Jaguar's dial-up internet link;[1] however, the Jaguar internet link was never completed or released, so Iron Soldier was released as a single-player game only.
