A.C.E.: Another Century's Episode R

Another Century's Episode: R (アナザーセンチュリーズエピソード アール Anazā Senchurīzu Episōdo R), abbreviated as A.C.E.: R, is a mecha action video game developed by FromSoftware and Banpresto and published by Bandai Namco Games. The game was released for the PlayStation 3 in Japan on August 19, 2010.

The main events of the game itself revolve around an original timeline again completely independent of all other featured series. In this timeline humanity has expanded beyond the Solar system, with planet Area becoming one of those resulting colonies. But somewhere along the line the Seasons, androids originally built to help the colonists settling on Area, rebelled against their human companions. Leading a robotic army collectively known as the Icon, the Seasons successfully wiped out the humans on planet Area, but there is one last trick up the colonists' sleeves: they made a data copy out of one of the Seasons androids and entrusted it, named Autumn-4, with genetic seeds of themselves as well as a trans-atmospheric battleship Ark Alpha. The intention was for Autumn-4 to take the gene seeds as far away from the Seasons' grip as possible so that the now-deceased colonists can be reborn on a safe world. Soon after commencement of Autumn-4's mission, however, Ark Alpha was intercepted by a fleet of Icon warships led by Winter-1, head of the Seasons. Overwhelmed by the numerically-superior enemies and in desperation, Autumn-4 activated a device within Ark Alpha called V-Drive, which has the ability to create a blackhole-like portal to parallel universes: it worked, with Brunhilde emerging from the portal and repulsing the Icon fleet, but also unintentionally caused characters from other timelines to be transported to planet Area as well. To make the matter worse, the energy discharged by Brunhilde in the process affected Autumn-4's memory circuits and corrupted her record of the event, leaving her unable to explain to all the people who now find themselves stranded in a foreign universe as to what has transpired.
