DIDACT BOSS FIGHT in Halo 3 ULTIMATE FIREFIGHT MOD?!(Sandtrap)

Today, my friend and I play Halo 3 Ultimate Firefight Sandtrap mod on Halo: The Master Chief Collection! Made by Weaver900. This round we fight the Halo 4 Prometheans with the final boss being the Didact himself! We did end up having the Grizzly Tank from Halo Wars so... things got chaotic! I hope you enjoy the video! ‪@weaver900‬ #halomcc #mods #halo3
