Forerunner Warrior-Servants tested themselves in this arena before facing the Flood.

Coliseum is an arena multiplayer map that can be played in Halo 5: Guardians. It is set in an unknown Forerunner facility.[1]


“The first incursions of the Flood into the Forerunners’ outer territories signaled the beginning of a centuries-long war. Although they immediately summoned the full strength of their navy, most Warrior-Servants recognized that this conflict would be won or lost on the ground. Hidden safely in the shadows of the Burn, this military compound provided a necessary proving ground, strategically honing those who were destined for sacrificial glory.”
— Cannon Fodder, Rhine Installation[2]


  • There are a few bird-like creatures flying above the map.
  • There is a robot like creature underneath each base, that disappears under a hatch when the player gets too close. Shooting them and/or throwing grenades appears to have no effect.
