The Rig

The Rig is an arena multiplayer map that can be played in Halo 5: Guardians. It is set on an unknown mining platform on the planet Meridian.

Description
"Meridian’s original inhabitants enjoyed the moon’s temperate climate and fertile land for decades. But when the Covenant unexpectedly arrived in 2551, the world’s impressive population and robust economy were suddenly laid low, glassed to the brink of extinction. Now, still clinging to the ghosts of commerce, mining platforms like this one scour what remains of the world’s surface—a tragically hollow attempt to resurrect the colony’s past opulence and splendor."
