About

OpenTS is a community-led, open-source reconstruction of Command & Conquer: Tiberian Sun that rebuilds the engine as a standalone program rather than patching the retail executable. It targets Tiberian Sun 2.03 Firestorm and is based on Electronic Arts' GPL-released source for related Command & Conquer games plus Tiberian Sun-specific reverse engineering. Release 0.1.0 runs the full game, and the project is licensed under GPL version 3 or later.

How it differs from the original

The renderer uses bgfx and supports modern resolutions through 4K, including ultrawide. The project also aims to add modding capabilities and new engine features beyond the original game.

Getting started

Install Tiberian Sun from Command & Conquer The Ultimate Collection on Steam or the EA App, extract the release zip into the Tiberian Sun game directory, and run Game.exe.

History

OpenTS continues a community reconstruction preserved in the TibSun archive, built from Electronic Arts' published source and completed through reverse engineering against the original executable.

Known issues & limitations

Play network games with peers on the same platform; a platform mismatch can cause desync.
There is no supported native Linux build; Wine may work.
LAN multiplayer has had more limited testing than the campaigns, skirmish, and save/load.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game.

Use Windows 10 version 1903 (build 18362) or newer; earlier versions are unsupported.

Features

The project runs the full game, including the GDI, Nod, and Firestorm campaigns, skirmish, and save/load.
The renderer supports modern resolutions through 4K, including ultrawide.
LAN multiplayer is available, but has had more limited testing.

How to install

Extract the release zip into the Tiberian Sun game directory, then run Game.exe.
Download a release zip from the releases page; releases are the recommended builds.
No installer, extra runtime library, or launch argument is required.
