"Pit-Fighter is a 1990 arcade by Atari Games, notable for its early use of digitized live actors. The graphic animation for the player character(s) and opponents were created through a bluescreen process, where the various poses & moves of the characters were acted out by hired actors in front of a video camera. The game's on-screen character animation are replays of the actual footage, not a rotoscoped (redrawn) animation as was common in other games. Live-action shooting reached a brief highpoint with later arcade titles such as Mortal Kombat and NBA Jam, before gaming trends shifted away."
