Dual Valley is a fictional location, loosely based on Wilpeana Pound in South Australia. The valley is surrounded by cliffs, with train lines weaving through the hills, over trestle bridges and tunnels through goldmines leftover from the Gold Rush of the 1850s.

This is a remote location in the middle of a natural crater and the player starts with basic equipment that looks like it has been sitting around for years. The trains are the main way to sell items and diesel is expensive, so it's worth making your own.

The goal is to grow the town and work towards supplying the local wedding reception with gold rings, diamond rings, wedding dresses, tuxedos and food to feed their guests.

This map can also be played in a multiplayer, 1v1 map where you start across the river from each other. You both start with the same items and there are two of everything; two train lines, two mines, two custom stone processing plants, two custom diesel plants, two custom jewellery productions, and two custom tailor shops.

- 37 Fields
- 2 Train lines - Main sell point
- 2 Custom small diesel locomotives to navigate the tight turns
- 2 Underground mines to collect stones on the trains
