The player took the role of Ivan Popovich, a Russian soldier controlling a giant mechanical suit, defending the Earth from robotic aliens.
The game was not a commercial success. The graphics were good for its time and there were a variety of weapons, but was incredibly short - the entire game consisted of five zones (Russia, Saudi Arabia, France, USA and Japan) each taking about 10 minutes to complete.
The game also has an interface at the end of each zone allowing you to spend the game's form of experience points (power cores) on upgrades and weapons.
But there were only a small selection of upgrades and weapons as well, so this is akin to the game's shortness.
