It's the 23rd century: The earth's natural resources are virtually exhausted, and the ruling multinational conglomerates are searching for new raw material deposits in space in order to avert the impending catastrophe. One planet turns out to be a real El Dorado in this respect, but as the human conquerors in their armed mecha encounter the extraterrestrial inhabitants, all-out war ensues.

The player must research into new technologies and continue to improve his mecha to survive. Battles are thereby fought in wonderful 3D landscapes - against the merciless AI or other human opponents in the various multiplayer modes.
