Akira (prototype)

Akira (Cancelled) is an Action game, developed by Black Pearl and published by THQ, which was cancelled before it was released.
"While a prototype of this version was showcased at the Summer Consumer Electronics Show (SCES) in June 1994, the prototype covered here predates that one, as it has several notable differences that would be remedied in time for the public showcasing." (via The Cutting Room Floor)
