Another World, known as Out of This World in North America, is a 1991 cinematic platformer action-adventure game designed by Éric Chahi and published by Delphine Software. The game tells a story of Lester, a young scientist who, as a result of an experiment gone wrong, finds himself on a dangerous alien world where he is forced to fight for his survival.

Another World is a platform game, featuring a control scheme where the player uses either the keyboard, joystick or gamepad to make the protagonist run, jump, attack and perform other, situation-specific actions, such as rocking a cage back and forth. In the initial part of the game, the player's character Lester is unarmed. He is able to kick at small creatures, but is otherwise defenseless.

Later in the game, the player acquires a laser pistol from a fallen foe. The pistol has three capabilities: a standard fire mode, the ability to create force fields to block enemy fire, and a powerful charged shot that can break through force fields and some walls. Enemies also have the same capabilities, requiring the player to take advantage of the three gun modes and the environment to overcome them.
