Outland

Outland is a platform game developed by Housemarque and published by Ubisoft. The game combines two-dimensional platforming with a polarity system similar to Treasure's Ikaruga and Silhouette Mirage. Outland was released on April 27, 2011 for Xbox 360 via Xbox Live Arcade. The PlayStation 3 version, which was supposed to be released the day before, was delayed because of the 2011 PlayStation Network outage before being released on PSN on June 1, 2011. A Microsoft Windows version was released on September 29, 2014, followed by a Mac OS X version on December 21 of the same year, and a Linux version on February 25, 2015.
