The game, from Thai developer Extend Interactive is the first of a "full-featured" episodic side-scroller.
The game has won prizes already - picking up first place at the recent XNA Dream Build Play Contest.
We'll leave the press release to explain the rest:
In the traditions of retro classics, you play as Ares, an advanced combat robot sent on a mission to rescue taskforce members who were trapped while conducting an investigation to find out the extent of damage sustained by the space station.
Annihilate countless robots, recycle their parts to make incredible items and take on gigantic bosses in this 3D environment side-scroller.
