Unit 16 is a robot NPC in Robot City. After the corruption of the Master NXT, Unit 16 witnessed the corruption spread through the citizens of Robot City, turning them into Infected Citizens. Without a proper firewall to contain the spread of Maelstrom, Unit 16 sends players to smash three Infected Citizens. Once this task is complete, Unit 16 rewards players for their efforts with a Robot City Rocket Nose Cone. Then, Unit 16 asks players to deliver a welder to Unit 32 so that he may complete the structure in Central Park.
