OpenCaptive Wiki

OpenCaptive is a C/SDL3 reimplementation of Captive (1990) and Liberation: Captive 2 (1993) by Tony Crowther, originally published by Mindscape.

The project targets source-level accuracy against the original DOS, Amiga, Atari ST and CD32 releases. No original game data is distributed; users supply their own files, verified by SHA-256 content identity.
