- For the Battledome a multiplayer map in Ratchet: Deadlocked, see Battledome Tower.
The Battledome (originally named the Colosseum)  was the DreadZone Station's arena, where most of the battles on DreadZone took place. Three of the Exterminators were defeated in the Dome (Reactor, Eviscerator and Ace Hardlight), as well as DreadZone's founder, Gleeman Vox. Shellshock; however, was defeated in the Kronos Cathedral. It was completely destroyed when Vox blew up the DreadZone Station in a failed attempt to kill Ratchet, who had defeated all four of Vox's acclaimed Exterminators.
