Added HostileNegotiator's flood collision fixes, flood combat forms should be more consistent to kill now (no more randomly tanking 3 energy sword hits).
Other bug fixes and balance changes

Major Update:
Added 6 new Banished mini-bosses to Ultimate Firefight Sandtrap, each with their own unique upgraded human power weapon.
Added 6 new unlockable heroes to Ultimate Firefight Containment (The same characters as the new mini-bosses)
Added early boss fights to Ultimate Firefight Containment
The new arena stand-in will now play on Wave 6 of each round for Ultimate Firefight Containment
Added many new events to Ultimate Firefight Containment
Heavy Brutes with flamethrower hunter canons can now be recruited as allies in Ultimate Firefight Containment
Many bug fixes and other minor updates

All Heores and the Partner in Ultimate Firefight Sandtrap now use a randomized set of weapons tailored to each Hero (E.G. Johnson has chance of spawning with Spartan Laser)

Added echo482's Spartan animations to all Halo 3 based Spartan rewards and heroes, and greatly buffed reward Spartans.

Reworked headshot damage- DMR, Carbine, Needle Rifle, Stalker Rifle, Magnum and Mangler headshots all now penetrate grunt and skirmisher helmets, instantly killing them. Sniper Rifle, Beam Rifle, and Binary Rifle headshots also do this, as well as penetrating Brute helmets as long as their shields break, allowing for one-shot kill sniper headshots on most Brutes.

Buffed friendly elite majors to have slightly more health.

Added Ravager to Sandtrap map

Battle Rifle updated with new shaders, based off of Atlas' Halo 2 Anniversary Weapons for Halo 3 BR.
Implemented attempted fix for softlock when starting on later rounds (If this doesn't fix it, you can still get past the softlock by finding one of the artifacts and picking it up).

Reduced filesize of mod by using Shared map.

Cut Engineers from Sandtrap as they were causing some instability.

Added PRT to RPA60's weapon models (makes them look nicer)
Updated the testing version of the Library
Added a new version of the deployable cover to certain Promethean enemies
Added Vortex equipment to Containment
