Project Gravemind — Update! ❤️WE DID IT! WE BROKE HALO 2'S 16-PLAYER LIMIT. Multiplayer: 24 players. We tested matches with 24 players alive and synchronized on Lockout, Midship, and Coagulation. We had to overcome several engine limitations: Expanded network messages that only supported 16 players. Adapted player identification, which used only 4 bits. Fixed memory issues that caused crashes when player 17 joined. Removed the limit of 16 simultaneously living players. Campaign co-op: up to 16 players. We tested the campaign with 16 synchronized players at Cairo Station. We fixed action synchronization issues and adapted spawn points to support additional players. How did we do it? Through reverse engineering of the MCC version of Halo 2's engine, we tracked down the issues and applied in-memory patches at startup, without modifying the original game files. To test 24 players on a single PC, we used split-screen: 6 game windows with 4 players each. I never imagined we'd get this far. What once seemed impossible is now a reality, and this might only be the beginning. H2: Project Gravemind Built by the community, for the community. 💚 #Halo2 #ProjectGravemind #HaloMCC #HaloCommunity
