About
Chasm: The Rift is a 1997 MS-DOS first-person shooter developed by Action Forms and published by Megamedia Corporation. PanzerChasm is a free recreation of Chasm: The Rift built on SDL2, with optional OpenGL 3.3 rendering, that runs on the original game's data. The repository also contains related tools, and the project is licensed under GNU GPL v3.
How it differs from the original
It adds a developer console with command autocompletion, plus command-line options for loading alternate data files, add-ons and start-up commands.
Getting started
Copy CSM.BIN from an installed original game (such as the GOG release) next to the PanzerChasm executable and its shaders folder, then run it. Controls are WASD with the mouse, Space to jump and 1-8 to select weapons.
Additional notes
- Feature
- Alternate game data files (such as a Russian CSM.BIN) and add-ons can be loaded via command-line options.
