Steampunk Sewers
Steampunk Sewers is a machine that was built to be drained and never was. Cog shooters line the walls, hammer bots wade through the water, and every third room is somebody’s workshop with a boss bolted to the floor.
The last fight turns the room itself into the attack: the Cannon Blaster 2000 barely has to aim to hurt you.

Mobs
Cog Shooter
The Cog Shooter in Steampunk Sewers has two pink-outlined cogs. Its ranged attacks allow more reaction time than earlier enemies and can fire twice. It pursues the closest player or highest damage-dealer unless taunted.
Fighter Bot
Fighter Bots in Steampunk Sewers have green outlines and carry swords. They pursue the closest player or highest damage-dealer unless taunted. Their base movement speed matches the player’s, so outrunning them requires a speed potion or movement spell.
Hammer Bot
The Hammer Bot is a red wheeled robot in Steampunk Sewers. It brings its hammer down, picks itself up quickly and repeats. It moves and attacks faster than standard melee enemies. Circle its attack range rather than trying to outrun it; it targets the nearest or highest damage-dealing player unless taunted.
Spinner Bot
The Spinner Bot in Steampunk Sewers resembles the Hammer Bot but carries a sword. It stops to charge, then swings in a circle multiple times. It pursues the closest player or highest damage-dealer unless taunted.
Bosses
Cyclops Siege Bot
The Cyclops Siege Bot is a spider-like machine with a green eye, found in the second room of Steampunk Sewers.
Evil Scientist
The Evil Scientist waits in the sixth room of Steampunk Sewers, carrying a Mighty Fusion Spellblade and wearing a modified Inventor’s Warrior Set.
Cannon Blaster 2000
The Cannon Blaster 2000 is a spherical machine with two cannons, four mechanical legs and a yellow eye. It waits in the eighth room of Steampunk Sewers.

Trivia
The Robot Gladiator’s boss write-up in the companion documents refers to an attack as both Energy Rope and Chain Reaction. The page follows the attack table, which names it Energy Rope.
Wave Defence does not apply to this map.
The Fighter Bot has a green slit for eyes and punches; the Cog Shooter has a purple one and fires a line from range; the Spinner Bot and the Hammer Bot are both tanks carrying a blade or a hammer on top and hitting with a small circular area of effect.
The Cannon Blaster 2000’s third phase makes the whole map an area of effect, leaving only the safe zones around the edges of the room.
