Prove your merit to the New Monarchy in pure combat. Kill everything. Watch your back.
― In-game description

Rumble is a six-player free-for-all Crucible gametype.

Each kill awards 100 base points, with an additional amount allotted per method of kill. Head shots, melee kills, and grenade kills add 10 points, while heavy weapon kills add 15 points and super ability kills add 25 points. An assist grants 25 base points. If a Guardian kills the leader (the player with the most points), an extra 50 point bonus is added. Killing sprees (achieving five kills without dying) adds 25 points.

If a Guardian dies, they will have to wait three seconds before respawning. After the allotted time has passed, a 10 second timer will appear. Once that time has passed, the Guardian will automatically respawn.

The player can receive a medal at the end called Sum Of All Tears for winning with a score higher than the sum of all enemy scores.
