Local second-player scripts: Player 2 can join storyline, vigilante and firefighter missions, and another loader restores 16 cut PS2 missions. Needs CLEO and a second controller; may only work on v1.0.

About this project

Server-based multiplayer where players explore and play minigames or roleplay. Search results do not show shared story-mission play, so this does not count as campaign co-op.

About this project

The most complete story co-op attempt for San Andreas (GPL-3.0, 600+ stars, in active development). Syncs players, weapons and every shot, vehicles with tuning, explosions, separate peds, EnEx and mission markers; NPC sync and side missions are still in progress. Started through its own launcher, which runs gta_sa.exe with the mod DLL injected, plus a server.exe.

About this project

Host plays as CJ, friends join through a server browser, and mission peds, vehicles, characters and subtitles are mirrored. Networking has automated tests, but the in-game part had not yet been run inside GTA SA when the README was seen. The repo returned not found on API lookup, so check it still exists.
