Steam Alley is the most mechanical area in the Downtown area, however the actual "steam alley" is a brick path leading around, and to Tech Square and Offworld Plaza. In the southeastern part of the area is the Dark Engine, a giant mechanical Terrafuser. Fusion Hoss Delgado is hiding in the ventilation area of the Dark Engine and Fusion Numbuh 1 is here plotting and trying to tamper with the Great Machine behind City Hall. A very large amount of the zone is currently becoming an infected zone; the infection of Steam Alley takes up more than a half of the zone. There are some Monkey Minions here that are probably scouting for Mojo .
