Offworld Multiplayer is now FREE!

Offworld Trading Company multiplayer is now free-to-play! To get a key for a multiplayer-only version of the game, simply sign up to our company mailing list.

Soren posted his thoughts on moving the game to free-to-play on his blog. Here’s an excerpt:

I’ve had a long-running lovehatefear relationship with free-to-play games; indeed, I even made one! However, after they did end up either eating or expanding the industry (depending on one’s perspective), it is clear now that there are different types of free-to-play games and different reasons to use the model. Our model is the simplest, dumbest available. Multiplayer is free, and we are developing new DLC and retrofitting old DLC to be mutually exclusive so that players can buy whatever parts of the game they like. The most obvious purchase is the base game itself, which unlocks all sorts of things, but there are other attractive options which can be bought and played without the base game:

Blue Chip Ventures, a series of scripted scenarios and challenges that help teach the game

Market Corrections, three scripted campaigns that give access to that side of the game

Limited Supply, an alternate version of Offworld which takes away the market in favor of resource puzzles

There’s even a cosmetic-only set of skins for special buildings called Conspicuous Consumption. (See, we were thinking ahead!)

I’m very curious to see what will happen. In the two hours since the free version came out, our player base has already quadrupled. Hopefully, multiplayer games will now always be available for budding tycoons.

Offworld Trading Company Update 14

  • Tutorials have been updated
  • Players can now see their Masquerade name while when playing in Masquerade mode
  • Some colony classes have had their resource price minimums lowered. In the Daily Challenge mode the best move was sometimes just throwing down a large number of mines or quarries on an easy to access resource, and because the resource would never drop below $30 a player could just sell that one resource until they had won. This change to address that situation and encourage more interesting strategies.
  • Increased precision of the server game timer.


As expressed by the community recently, extra claims can be extremely powerful. In fact, this reward for founding late was so strong that many players would only found without it in the most dire of circumstances. Early claims are being adjusted so that in games of 4 players or less everyone will receive an extra claim eventually.

  • Last four players to found now all receive a free claim (last to found on HQ2, then HQ3, HQ4, HQ5) regardless of number of players in the game

Several small changes are being made to Black Market items to add consistency and bring costs in line with the power each item brings. Spies and Holograms will now have a cooldown, preventing a player with an early lead from taking them all cheaply to get a significant advantage. Meanwhile, Return a Claim and Core Samples have had their cooldowns reduced to encourage their use.

  • Return a Claim Black Market item can now be purchased when in D Debt
  • Changed Black Market cooldown for Bribe a Claim to 90 seconds (up from 60)
  • Changed Black Market cooldown for Holograms, Spies, Return a Claim, and Core Sample to 30 seconds.
  • Pirates now steal 200 resources
  • Pirates and Magnetic Storms are more likely to appear

Patents are receiving some small adjustments, focused on making energy slightly more accessible and bringing Transparent Aluminum’s power down.

  • Energy Vault now produces 2 backup Energy (up from 1)
  • Transparent Aluminum now costs 60 chems (up from 40)
  • Perpetual Motion now costs 40 chems (down from 60)
Bug Fixes
  • Nomads now receive the correct Black Market time when founding
  • Infinite Challenge Leaderboard now properly updates when played from the Ranked Queue
  • Geothermal Borehole Auctions will no longer occur on maps where no Geothermal Vents are present
  • Overflow bug and formatting fixed for very large amounts of cash
  • Players can once again see number of players in FFA queue while in the 1v1 queue
  • Fixed an error with “Infinite Win (Io)” Achievement
  • Fixed border color artifacts on Medium and Low Rendering Quality

Limited Supply DLC Now Available!

Stock Markets and Rival Businesses Aren’t Your Enemies Here. In “Limited Supply,” your main goal is simple: survive.

  • New Scenarios
    Experience over a dozen new missions, each with their own challenges! Each new scenario has unique rule sets and locations that will take you on a fun and exciting journey as humanity settles on Mars.
  • Changing Environment
    As you progress through the scenarios, you will face different restrictions on what you’re able to buy and sell. In order to survive, you’ll have to constantly re-evaluate your strategies and adapt to each new location and challenge.
  • Evolving Technologies
    In a normal game of Offworld, you’d build up your business so that you could buy out your competition. Instead, you’ll need to meet a list of objectives set by the colony. As you progress, the tech you have access to becomes more advanced – but, so do the colony’s requests!
  • Unique Challenges
    This DLC breaks the core rule of Offworld Trading Company, which is “buy what you want, when you want (as long as you’ve got the cash).” Each scenario has a different ruleset that restricts what resources you’re allowed to buy and sell – even essentials like food, water, fuel and oxygen! Failing to maintain a steady supply and manage your resources effectively could mean catastrophe for the colony – and for you.
  • A New Way to Play
    Instead of the head-to-head “buy or be bought out” combat in a normal game of Offworld, this DLC lets you experience the game through a series of puzzles needing to be solved. There is no stock market, no competing businesses – your only competition here is Mars itself.

Offworld Trading Company – Jupiter’s Forge

Prudent business decisions take you to Jupiter’s moon, Io, to harvest its resources and keep an edge on your competition. Io’s 42-hour days and lack of an atmosphere means that you’ll have to change your strategy and choose what to build very carefully! Radiation storms, sulfur frosts, tremors, and harsh landscapes threaten your business model and force you to adapt in order to survive.

Take your adventure to Io
Explore Jupiter’s volcanic and volatile moon where energy is plentiful, but life support is so difficult that it makes Mars look like a paradise.

Adapt to new Resources
On Io, production works a little differently. There are plenty of new sources of power, but basic human needs – like water – simply don’t exist. Priorities for what you build and harvest on Io are vastly different from Mars or Ceres. New resources like basalt exist only on Io and will let you build new structures and adapt to the lack of other materials.

Attempt the Infinite Map Challenge
Compete against the rest of the community in this unique set of challenges. Each map evolves, becoming more difficult than the last – can you fight your way onto the leaderboards? Push yourself past the competition and see how many maps you can conquer before the harsh environment of space gets the better of you.

Conquer the New Campaign
Show that you have what it takes to build your business on the harsh environment of Io. Snag your resources before your adversaries do and prove to everyone that money talks: you made it on Mars, and you can make it on Io, too.

New Faction: Diadem Trust
An elite business group with grand visions, they are ready to crush any other corporation that gets in their way. Advanced buildings like Hacker Arrays and Patent Labs are top of the line and grant them an edge on competitors. The patent race also means nothing to them – they can purchase a patent at any time, even if its already been researched by another player. It’s all legal, they assure you – read the fine print.

New Faction: Penrose Collective
Highly adaptable and influential, they intend to thrive on the harsh environment of Io. With the ability to found 2 headquarters at the start of the game, they are able to spread their operations across an already depleted environment in order to afford them access to more resources. When resources deplete on a claim, the Collective simply trades it in for a more profitable spot.
