Another World, also known as Out of This World in North America and Outer World (アウターワールド) in Japan, is a 1991 cinematic platformer action-adventure game designed by Eric Chahi for Delphine Software. The game tells a story of Lester, a young scientist who, as a result of an experiment gone wrong, finds himself in a dangerous alien world where he is forced to fight for his survival.
Originally developed on an Amiga for the Amiga, Atari ST, Apple IIGS and DOS platforms, the game was widely ported to other contemporary systems. Later efforts resulted in several game engine recreations for the game that permitted it to run on modern computers, consoles and mobile phones. In 2006, Chahi independently released a 15th Anniversary Edition for Windows which allowed the game to be played on modern computers with original or enhanced visuals; following up in 2011 for its 20th anniversary, ports of the game were prepared for iOS and Android based devices.
Another World was highly innovative in its use of cinematic effects in the graphics and cutscenes, which granted the game a praise amongst critics and a commercial success. It also influenced a number of other video games and designers.
