In the race to colonize planet Mars, everything is up for grabs.

Offworld Trading Company’s quick and intensely competitive matches pit up to 8 players against each other on randomly generated maps. Players must quickly determine the best path toward building a self-sufficient colony that can extract the abundant Martian resources while maintaining profitability – and surviving the “talents” of shady black-market characters who are all too happy to raid any player’s shipments or smuggle a paralyzing EMP device into any colony for the right price.

The Map Toolkit DLC for Offworld Trading Company allows players to build their own maps to share with friends and rivals using the new map editor and adds dozens of new maps based on real locations, many of which enhance the campaign.

“Players can have a great time creating their own maps from scratch,” said Soren Johnson, lead designer of Offworld Trading Company, “but we also wanted to give players some maps of real Mars locations, just to get them started.”

The Map Editor allows players to explore plenty of different options when creating a map. From larger design details such as creating deep canyons or huge plateaus, all the way down to the finer details of where resources can be found and how abundant they are, players will be able to create a unique map that they can then share with others.

Unlike traditional RTS games, there are no military units and what you need to win can change at a moment’s notice because on Mars, there are no rules in the free market. None of the 13 resources is more powerful than any other, and everything is for sale. Players gain cash by selling excess resources like carbon, fuel, and silicon on the open market, and spend it buying the resources they’re short on. Prices fluctuate in real time forcing players to adapt their strategy; dump a bunch of iron on the market and its price will crater, making other players’ stockpiles worth much less in the near term.

The game is won when the ultimate cutthroat capitalist completes buys out the stock of all their rivals, thereby seizing control of the entire planet’s economy.

In Offworld Trading Company, the marketplace is the battlefield.
