Strania: The Stella Machine, the new shoot'em up from Japanese developer G. Rev (Senko no Ronde, Border Down) that promises "retro-style graphics and old school shooting action", released to Xbox Live Arcade today across all major territories.

The game features sword-wielding mechas, co-op support both locally and online, and an "Over Dose" feature that gives players limited invulnerability for a short period of time while multiplying their score.

As shown at the end of the above trailer, G.Rev is already working on a downloadable content release called Side Vower for Strania, which will allow gamers to play as the opposing forces from the original game, experiencing the story from the perspective of the Vower army.

You can download Strania for 800 MS Points or grab a free demo at the XBLA marketplace.
