Back in March we announced that Square Off, Gnomic Studios' popular indie game for Xbox 360, was coming to Windows Phone. We wouldn't lie to you. Just two months later, the game is now available on the Marketplace.

Square Off is a twin-stick shooter (now without physical sticks). Players take control of a Square Avenger who straps on a jetpack, a gun, and a smile in order to save the earth from alien invasion. Square Off has seven levels and a tutorial level. After each stage ends, the player can choose to Fight On and tackle endless waves of enemies until the Square Avenger is finally overwhelmed. The game features impressive 2.5D graphics in which 2D cartoon characters battle in front of detailed 3D backgrounds.

We’ve already put both console and mobile versions of Square Off through their paces. Check back this afternoon for our full Windows Phone review.

Square Off costs $2.99 and there is a free trial. If you agree it’s hip to be square, grab it here (Zune link) on the Marketplace.

Note: Daniel Rubino here, been playing this for a week--you'll definitely want to try it. Soo cool.
