Heart of the Alien

Another World chronicles the story of a man hurtled through space and time by a nuclear experiment gone wrong. You assume the role of Lester Knight Chaykin, a young physicist. You’ll need to dodge, outwit, and overcome a host of alien monsters and deadly earthquakes that plague the alien landscape you now call home. Only a perfect blend of logic and skill will get you past the deadly obstacles that lie in waiting. This version of Another World is based upon the port of mobile phones, adding better graphics and resolution. It also has the new areas and enemies from the console versions.

Heart of the Alien is a sequel to Another World and continues the story directly from where the original ended. The game switches the player's role from Another World; this time the player takes control of Buddy, the main character's alien ally from the previous game.

Out of This World (Another World in Europe) is a cinematic platformer that uses vector-based graphics and rotoscoped animations to deliver a minimalistic yet expressive visual style. It features a combination of action, platforming, and puzzle-solving mechanics, with a deliberate lack of HUD and textual guidance. Gameplay emphasizes trial-and-error, timing, and exploration, with a limited checkpoint system. In 2005, a homebrew port of the Atari ST version was released for the Game Boy Advance, officially allowed by Éric Chahi to be published with the original assets.
