GitHub — Tribes 1 engine source code
Source-code repositories, not runnable game files — a different class of archive. These are C++ sources for the original Starsiege: Tribes (pre-Instant Action) client, built on Dynamix's Darkstar engine, and they form one chain: TribesRebirth by AltimorTASDK (the partial source, 2015), tribes1 by Imago (2023, the fork that added Visual Studio project files and first actually built, plus Imago's own Tribes tools), and Darkstar by mortarturret (published 2025, whose tree is byte-identical to Imago's but for one project file). That order is what the community reports — "MortarTurret did not get that from Altimor. He got it from Imago, who he got it from Altimor and was able to get a build going" (Link, PlayT1) — and the git hashes agree. Because such repos carry legal risk and can vanish from GitHub without warning, each is captured as a complete **git bundle** — all branches, tags and history in one self-verifying file — pinned to an exact commit and integrity-gated by the bundle's MD5 in the capture manifest, exactly like every other binary here. Rehydrate any of them with `git clone <name>.bundle`. No license is stated upstream; preserved as-is for study and credited to its author, with the pinned commit and upstream URL on each file's page. To refresh to a newer upstream commit, re-mirror and re-bundle.
