Heart of the Alien: Out of this World Parts I and II — About this game
Heart of the Alien follows the escape at the end of Another World, placing the player in control of Lester's alien companion Buddy. Cinematic platforming and environmental danger drive the sequel, with progress often depending on noticing how a scene's obstacles fit together. Buddy's physical abilities and whip-like weapon give the journey its own feel. This CD package also includes the original adventure, so its two parts have different protagonists. Choose the intended part before following a route or applying a control guide.
