Another World, known as Out of this World in the US and Outer World in Japan, is a 1991 cinematic platformer designed and developed by Eric Chahi. The graphics and box art were designed by Chahi, while the music was composed by Jean-François Freitas.

While not a great commercial success, Another World was innovative in its use of cinematic effects in the graphics, sound and cut scenes, with characters communicating through their facial features, gestures, and actions only. This cinematic style granted Another World cult status amongst critics and fans.

The protagonist of the game is Lester Knight Chaykin; a young, athletic, red haired physicist. Lester arrives at his high-tech underground laboratory during a thunderstorm, and continues to work on his experiment using a particle accelerator. Right before the particles reach their intended destination, lightning strikes the lab and interferes with the accelerator causing the unforeseen teleportation of Lester to a barren alien planet.

The player can control Lester using the keyboard or gamepad using four directions buttons and two action buttons: one for main actions, and one for jumping. Depending on the player's current position, movement, and status, the main action key performs a variety of actions including attacking and interacting with Lester's environment. At the start of the game Lester can only kick to attack, but later he can acquire a gun. While the movement keys normally make Lester run, the game also features sections where the player must swim, roll, or drive a vehicle. The player only has one life, but there are multiple checkpoints he can return to by entering the relevant pass code given at each one.
