Exception is a precision 2.5D platformer that pushes the genre into new territory with dynamic levels that flip, spin and transform during gameplay. The sidescroller genre has been largely forgotten save for retro-styled games. Exception attempts to meld the blistering speed of classic 2D gameplay with the limitless creativity offered by modern 3D graphics. The game is set inside a computer riddled with malware and viruses. The player plays the role of an anti-virus program and is charged with seeking out and destroying all remnants of the malware to prevent a catastrophic computer crash.
