Through your efforts as the Resistance Iron Soldier pilot, the Iron Fist Corporation has been destroyed. In its place the Resistance has set up a democratic government by the name of the United Republic. But all is not well within the republic. Iron Fist Corporation's longtime rival PENTA has decided to take advantage of the situation and is attacking. You must once again pilot your giant robot as you attempt to defend the fledgling republic from PENTA's aggressions.
Iron Soldier 2 is a first-person 3D giant mech game. Players must pilot their building-sized robots in a variety of missions ranging from search-and-destroy to surgical attacks to defending objectives. Starting with a limited set of weapons, players can collect more armaments throughout the game. Each weapon can be mounted on a certain part of the robot's body, but once mounted, no other weapons can be placed there. So, while there is a wide range of weapon configurations, not every weapon can be combined with others. Players can destroy buildings in levels to find crates containing new weapons and extra ammunition for current weapons.
Iron Soldier 2 is widely considered to be one of the best games released for the Jaguar; a cartridge and CD version exist (the cartridge version lacks the FMV sequence).
