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. The PlayStation 3 version, which was supposed to be released the day before, was delayed because of the 2011 PlayStation Network outage then later released in June 2011. A Microsoft Windows version was released on September 29, 2014, followed by the Mac OS X version on December 21 of the same year, and the Linux version on February 25, 2015. The game was removed from sale on Steam and the Humble Store in December 2018 but has since been added back to Steam.
