The entrance to Turnip Hill and the surrounding highway. Nearby is a small hangar and container yard next to train tracks.

Story
En-route to the Nuclear Power Plant, Mark encounters a roadblock and decides to proceed the rest of the way on foot, but finds the only way forward is through a very unusual tenement complex, entry of which is denied by a "border inspector". Mark will either have to find a six-pack of Osmo Olut beer to bribe the inspector, or get permission from one of the residents to let him in.

Turnip Hill Entrance
The start of one of the strangest areas in the game, some buttons on the doorbell panel don't work, others get no response, or make weird noises. Only 'Rob' a friend of Robin is helpful and tells the border guard to allow Mark in if Mark saved Robin in the beginning of Act 3. A 'passport' to Open Sewer can be picked up on a chair near the border inspector, while it serves no purpose or use in-game, it can be collected as a trophy to display in Mark's house after the credits.

Hangar Yard
A off-road train yard near the entrance to Turnip Hill. It appears someone has taken residence in the hangar and a nearby container, the container's occupant has a chatlog open with the hacker leader from Hacker Valley, a USB drive can be collected here for additional corruption evidence.
