Halo: Combat Evolved's Master Chief, Marines and Covenant, from your own MCC, fighting by the thousands in UEBS2.
Halo: Combat Evolved's armies in Ultimate Epic Battle Simulator 2.
Launch the game and a battle is already set up: the Master Chief and 200 Marines against 2,000 Grunts, Jackals, Elites and Hunters. You start inside the Chief, assault rifle in hand. Plasma bolts fly as soon as it begins.
Every Halo character is the real one, built from your own copy of Halo: The Master Chief Collection each time the game starts: models, textures and held weapons. UEBS2 animates them with its own soldiers' animations. Nothing from Halo ships with the mod.
