Resident Evil 2 (OpenBiohazard2)

WIN

OpenBiohazard2: an open-source reimplementation of the original Resident Evil 2 (Biohazard 2) engine, written in Go with OpenGL, that uses the files from the PC version. According to its task list, collision detection, event triggers, animation, pre-rendered backgrounds, and depth testing already work; still missing are audio (music and sound), the inventory system, enemy AI, puzzles, door transitions, sprites, and shadows. It’s played with the keyboard. Its only published release is 0.1.0 (May 17, 2024), an initial pre-release build for 64-bit Windows; otherwise it has to be built with Go. In September 2025 and in August, much of the code was reorganized and gained tests, OBJ model export, and debug markers for enemies; the latest change is from August 17. It comes with tools to unpack and convert the game’s files, and the project keeps a separate viewer for Biohazard 2’s scripts.

You needThe files from your own copy of Resident Evil 2 for PC, copied from its install folder into the project’s data folder. Plus 64-bit Windows for the published build, or Go to build it, and a graphics card with OpenGL.
