As we pointed out just yesterday, Ubisoft is bringing Japanese Rock-Em Sock-Em robot sim Amored Core for Answer to U.S. Playstation 3s and Xbox 360s. For those keeping track, this will be the thirteenth game in the series.

The giant-robot game will hit in September featuring online cooperative play, eight-player online battles, plenty of customization and one very convoluted storyline.

In the distant future, massive urban development and pollution have critically damaged the planet. There is widespread fear that the end of the world is approaching. The League corporations, a military superpower, control the planet's infrastructure and have forced most of the world's population to live in huge aerial communities, called Cradles, to avoid the contamination. The ORCA, a rebel resistance still residing on the surface of the polluted planet, have amassed a formidable arsenal and are mobilizing to attack The League's bases to put an end to their iron grip on the planet. As a mercenary armed with cutting-edge military robot technology, choose your side and defeat the other factions by harnessing the power of the deadliest and most gigantic weapons ever created by mankind.

Here's the full run down of game features ripped straight from Ubisoft's brand-spanking new fact sheet for the game:
