📋 About This Mod

Ultimate Firefight

Now on Steam Workshop! https://steamcommunity.com/sharedfiles/filedetails/?id=2898932491

Please note! This mod uses Halo 3 Co-Op netcode and therefore has issues with freezing and disconnecting if connection is not absolutely excellent. If you crash or disconnect after making significant progress and have the vod, I will include you as a runner up :)

Much of the following information is outdated, the mod page will be being revised soon following the release of the final update.

Please note that this mod is VERY big and VERY long, to see all the content will involve getting to at least Round 8, which can take many hours, and even then, after that point new features like multiple boss fights being possible at once will unlock.

Saving and quitting your game will allow you to continue where you left off in single player as long as you do not start another campaign mission. It is not recommended to play this mod all in one go, but good luck if you try :D

Featuring 10 waves, and infinite rounds of classic Co-Op or Solo Halo fun, with some new twists!

Normal difficulty recommended for Solo play.

This new mode features some unique systems:

Drop Pod Respawn system:

4KibAuc3jK4

When a player dies, they return to the nearest living player, or their dead body in style! This uses up a life however, so as cool as it is, you don't want to drop in too many times!

Hero System and Revive system:

8NadRm6TKQM

This map features 10 unlockable Hero characters from the Campaigns of Halo 3 and Halo 3: ODST! Unlock one at the end of each round, and they will stick with you forever! If they or a co-op partner goes down, you can revive them by walking up to them and holding RB! You hit marine? No? Then listen up!

Random Enemy Squads system:

Ultimate Firefight randomly selects enemy types to fill out the four squads that spawn each normal wave. As you progress from waves 1 to 10, you'll notice the enemies you face becoming tougher! That's normal right? Well, there is actually a tailored selection of enemies being spawned every wave! This system works on unlocks, after each wave you will unlock a new type of enemy, of which there are dozens! Higher waves will select more powerful enemies out of the ones you have unlocked, so as you progress through the rounds you'll be facing more diverse diverse waves full of different squad configurations and challenging enemies!

Random Reward system: 

At the end of every wave, you will be given a reward depending on how high of a wave you are on,
