Junk Force is a hand-drawn 2D precision platformer built on extreme, asymmetric cooperation. Two players control Noki, a relentless optimist, and Roboto, a machine modified to crush rebellions, whose sense of humor is as acidic as his disdain for the people of the Lowlands. Together they race through levels packed with hazards and enemies that will do anything to stop them before they reach the Citadel.
