About Offworld Trading Company
Offworld Trading Company drops players onto a colonized Mars where corporate titans compete for market dominance. The real‑time economic RTS emphasizes acquiring resources, producing goods, and manipulating a player‑driven market rather than combat.
The game includes a narrative single‑player campaign that reveals the origins of Martian corporations, a multiplayer mode for up to eight rivals, and the Jupiter’s Forge expansion that moves the competition to Io.
01 / THE GUIDE
Single‑Player Campaign
The campaign mode lets you discover the origin stories of the major Martian businesses, each led by a CEO with distinct traits and abilities.
Scenarios present varying market conditions and resource challenges, providing a narrative backdrop that guides your economic decisions.
- Compare CEO traits early to match your opening plan.
- Watch how each scenario’s market shifts before committing large investments.
02 / THE GUIDE
Multiplayer Dynamics
Up to eight players can compete in real‑time matches where the market reacts to each corporation’s resource choices and stock actions.
Alliances form and break quickly, and the market fluctuates based on collective production, making every game unique.
- Observe opponents’ stockpiles to time market interventions.
- Use short‑term alliances to destabilize a leading rival.

03 / THE GUIDE
Market Mechanics
The core system is a player‑driven market where supply, demand, and speculation act as your weapons and shields.
Over a dozen resources are available, and prices shift constantly, so each path to victory requires different production and trading choices.
- Track price trends before launching large factories.
- Diversify holdings to hedge against sudden swings.
04 / THE GUIDE
Jupiter’s Forge Expansion
The expansion adds a new campaign set on Io, Jupiter’s volcanic moon, where resources deplete over time, increasing competition.
Two additional factions, new patents, and harsher life‑support demands create a faster‑paced environment than Mars.
- Prioritize early extraction to stay ahead of depletion.
- Experiment with new patents to find efficient chains.

Audio and Extras
The soundtrack, composed by Grammy‑winning Christopher Tin, blends orchestra, piano, and synth elements for a retro‑futuristic tone.
Steam features include achievements, trading cards, a level editor, and cloud‑saved progress, supporting community‑created maps and replayability.
- Use the level editor to craft custom map challenges.
- Collect achievements to track your milestones.
