Inversus

Inversus is a minimalist action-strategy shooter for one to four players. Movement is constrained to opposite colors of a black and white grid. My walls are your paths and your walls are my paths. Each shot flips tile colors in an attempt to block, trap, and close in on the enemy. Firing a bullet opens up a path for you while also closing off a path for me. Both online and local couch play are supported. Fight for high scores on an ever-changing board. [Playstation.com]
