Originally created by Metanet Software, N has been downloaded over one million times, has thousands of custom levels, and won numerous awards, including the 2006 Slamdance Guerilla Gamemaker Competition's Audience Choice Award.

In 2008, Slick Entertainment developed N+ for the Xbox LIVE Arcade with additional development by Klei, which has since become one of the top selling games on the platform.

From the official website:

"In a futuristic world populated by inadvertently homicidal robots, a lone ninja must use acrobatic skill and iron-clad guts of steel to survive in this fast-paced, balls-to-the-wall action-puzzle platformer."
