Separators are robots built by the Master NXT to do his bidding. The Master NXT recently designed Separators to be stronger, faster, and unstoppable in comparison to his weaker minions, the Infected Citizens. Separators are now running amok in Robot City's Central Park, where they are disassembling the law-abiding Robot Citizens. To help stop the Separators in their rampage, Unit 64 asks players to smash a Separator.
