- Former World Description

Mechtropolis is the eighth world that the player will naturally encounter during the run.

The Vigilante Droid is the world-exclusive of Mechtropolis, being exclusive to this world. Higher variants of some droid types that appear become even more common, such as the Cryo 3.0 and Pyro 3.0.

Environment
Mechtropolis is an urban city street. The floor is a black road with grey walkways at the sides. The brick walls alternate between red and blue. Environmental objects that appear in this world include cars, trash cans, and street lamps. This world takes place at night, unlike most others.

Sentries
Some rooms contain Sentries. These sentries are essentially a Rapid-Fire Droid, but they do not aim at a player. Instead, they turn around while shooting rapidly. The direction in which they turn is determined by their color. After the room is cleared, the sentries will despawn.
