Based upon the iPhone game of the same name, Space Invaders Infinity Gene starts as classic arcade shooter we all know and love before evolving the into a singing, dancing 3D shooter. Necromachina, meanwhile, teases deadly animate cups. Chilling.

Descriptions from Square follow below, along with trailers for the two titles.

Necromachina

Platform: Xbox LIVE Arcade for Xbox 360
Genre: Action
Release: TBC

At the dawn of the 22nd century, an evil power brought inanimate objects to life, and they turned on humanity. Bridges, cars, cups--the whole of humanity's creations turned on their makers. But hidden amongst humanity's survivors, an elite unit of specially trained ninja known as Moondivers has been lying in wait for orders to reclaim the planet. Today, those orders arrived.

With legendary director Kouichi Yotsui (of Strider fame), Square Enix takes side-scrolling action games to the next level.
