Another World: 20th Anniversary Edition is the second remake of Eric Chahi's 1991 classic sci-fi platforming game titled Out of This World in North America. The 20th Anniversary Edition was first released for iOS and Android devices by DotEmu, allowing players to enjoy the game in either the original or updated HD graphics.
The game is a cinematic side-scrolling platformer where players explore 2D environments set on a mysterious alien planet. As Lester Knight Chaykin, players must escape a subterranean prison camp with the help of another alien captive by using their surroundings to avoid and overcome hostile wildlife and alien soldiers. Another World largely eschews HUD elements during actual gameplay, encouraging players to carefully observe the environments to discover the best way to survive and progress.
