About
Heart of the Alien was released for the Sega CD, where it was bundled together with Another World as a bonus title rather than being part of the same game. Heart of the Alien Redux is a from-scratch rewrite of Heart of the Alien for modern computers and consoles, built with CMake. It requires the player to supply the original Sega CD release's ISO and audio tracks, and as of version 2.0.0 uses SDL3 for graphics and audio, with configurable window scaling, filtering, joystick support, and input recording/replay for bug reports.
How it differs from the original
The remake reproduces the original game logic but requires separately supplied original game data rather than bundling any assets, and it deliberately excludes Another World, which was only included as a bonus with the original Sega CD release.
Getting started
You need your own copy of the original game's ISO and music tracks, named to match the expected prefix and placed alongside the program; command-line flags control fullscreen, window scaling, and joystick selection, and F5/F7 are used to quicksave and quickload.
History
The project's first public release was version 1.2.0; later updates added joystick support and visual scaling filters (1.2.2), and version 2.0.0 ported the engine to SDL3.

Additional notes
- Trivia
- A movement exploit that makes an enemy 'beast' disappear was confirmed to occur in the original Sega CD version as well, not just the remake.
