Hemorrhage AI Mayhem | Endless AI War

Hey guys, thanks for checking out my first ever Reach mod! I definitely enjoyed and learned a lot making this one! An all out war is taking place between the Covenant and UNSC in Forge World’s “Hemorrhage” section. Ground troops, vehicles, and aircraft are included. Everything is handled by my custom scripts, which will keep the fight going for as long as the game lasts. Reinforcements are flown in by dropship, and for the first time ever in my maps - dropships also fly in AI vehicles. CO-OP is fully supported too! Lock and load, but most importantly - have fun!


*This mod has been updated to be compatible with the Halo MCC patch released on February 28th, 2025. Everything is fully functional.*

• An endless AI War, with all troops and some vehicles being flown in via dropships.
  
• *NEW* My custom AI control switch system, that allows players to choose which AI infantry and vehicle squads can join the fight. You are the boss and are fully in control!
  
• Over 80 combatants that can optionally take part in the battle, with carefully staggered spawns and controls to not overload the Reach AI system.
  
• Pathfinding all over the Hemorrhage section of Forge World.
  
• Random compositions of AI squads, so every engagement is different each time.
  
• Random warthog spawning script - with chaingun hogs being most common, and rocket/gauss hogs being more rare.
  
• Custom placed Forge objects. (Bases, scenery, and more.)
  
• Ability to customize the experience by changing the game settings in the pregame lobby.
  
• Multiple respawn locations that can be chosen by each team’s players.
  
• CO-OP is fully supported with no AI desync! Play with or against your friends seamlessly!
  
• Full control over the AI difficulty. Choose between one of the four levels. The AI has been balanced best for Normal and Heroic, but all difficulties work fine.
  
• And plenty more to be experienced!

After subscribing to the mod on Steam and letting the download complete, launch the MCC with anti-cheat disabled. Navigate to Firefight, then Halo Reach Custom Firefight, and there should be an option to see Modded Missions. Choose “Hem. AI Mayhem”, and then select a gametype. Do not choose any game modes that include “generator defense” options enabled, as the map does not support generator placement (yet). Feel free to customize anything in the gametype options. If you want to jump in right away without customizing anything, I recommend choosing the “Firefight Classic” gamemode. Choose your difficulty (Normal or Heroic is recommended, but all work fine) and load in. You are now all set! To play on the Human team, choose red. To join the Covenant, choose blue. If you want to play with your friends, make sure everyone has the mod installed, and launches with Anticheat off. Join your friend’s lobby and proceed as defined above.



Originally, I had planned this entire mod to function just like my previous two releases. You would load up the map in Custom Games or Forge, and be allowed to mess around as you see fit. However during testing, I discovered that Reach works differently than H3. After the mod was compiled and loaded into the game, all of the AI scripts were stripped out of the mod. So some of the combatants would be flown into the match once, and never respawn again. Others would never appear at all. AI would not comply with team allegiance commands, and other annoying bugs. After doing some research, I found out that Reach multiplayer cannot currently support projects of this type. The good news is Firefight can! So I checked out some tutorials, and got the map up and running in Reach’s Firefight mode. I had to modify and strip out a lot of the Firefight functionality, so the map would play as I desired. This actually was a good thing in the end, as everything functioned as intended, plus now players can face off as Spartans with the UNSC, and Elites with the Covenant. Cooperative now works as well, without any annoying AI desynchronization! So a number of good things came out of moving this project into the Firefight ecosystem.
