OpenPREY: a replacement engine for PREY (2006)

OpenPREY adapts a Quake4Doom-derived engine to run PREY (2006) from the player's original installation on Windows, Linux and macOS. It checks the game's PK4 asset layout, supports its game-module loading model, and adds SDL3 windowing, modern display modes and diagnostic tooling.
