Justice League: Task Force
Justice League: Task Force, released in 1995, puts DC heroes and villains into a one-on-one fighting game. The roster includes Superman, Batman, Wonder Woman, The Flash, Aquaman, and Green Arrow on the hero side, with Despero and Darkseid as opponents. Each character has a story mode path framing their reason for fighting.
Blizzard Entertainment developed the Super Nintendo version of the game, which plays noticeably differently from the Genesis version (developed by Condor Studio, later acquired by Blizzard to create Diablo) in feel and visual style.
I was working on several games at once, and my contribution to this title was engine-programming and "glue screens", which is what we at Blizzard called all the interstitial screens that glue the game together (title screen, setup, etc.).
