Atomic Factory

Atomic Factory is the ninth world the player will encounter in a run. It is currently the last world with enemies, and the penultimate world if Null is considered a world.

Atomic Factory introduces the Reactor Droid, the world's special droid. It also introduces 3.0 variants of some previously encountered droids such as Rapid-Fire Droid 3.0 and Xero Droid 3.0.

Players can't warp while in the '''Atomic Factory. '''

Environment
Atomic Factory appears to be a factory working with radioactive substances. The ground is black and the walls are gray. Objects that appear in this world include conveyor belts and barrels. The world's environmental hazard is Radioactive Waste.

Conveyor belts are special platforms that move most objects on it in a specified direction with a speed of of ten studs per second. A player with a default movespeed can still outrun the conveyor belts when running against it, although they'll be slowed significantly. Droids with a movement speed of 10 or slower cannot move against the conveyor belts. Conveyor belts may spawn on the ground or on top of the walls.

Radioactive Waste acts like lava, burning the player on contact, but acid pools cannot be frozen by any means. They also burn the player in a slower rate, giving more time to react.
