Terraformers

Terraformers PC is a turn-based Mars colony builder that combines resource management, procedural exploration, city specialization, and roguelike replayability. Asteroid Lab developed the game, with Goblinz Publishing and IndieArk as publishers. The current storefront name remains Terraformers; there is no verified rebrand or replacement title, although the game is also sold through a complete Terraformers Collection containing the base game and three gameplay expansions.

Rather than simulating every detail of a real-time colony, Terraformers presents Mars as a strategic board of regions, cities, projects, and global terraforming goals. Its strongest appeal is the way each turn turns limited information into a meaningful planning problem.

Turn-based Mars colonization with a card-driven loop

Each campaign begins with a settlement, a leader, and an unexplored portion of Mars. You spend turns choosing from proposed projects, expanding into new regions, exploring landmarks, gathering resources, and responding to events. The core loop is built around resource conversion: power, food, science, support, and extracted materials must be directed toward immediate survival or longer-term growth.

Terraformers uses a card-like project proposal system rather than allowing every researched building to be constructed immediately. Projects are drawn from different pools as the game advances, creating a controlled element of uncertainty. The available options can include city buildings, regional buildings, and space projects, so every turn asks you to compare production, positioning, terraforming progress, and future synergy.

The perspective is an abstract, map-based management view rather than a character-focused camera. You inspect Mars from above, move between regions and cities, and use leaders, rovers, satellites, and buildings to reveal useful locations. Exploration exposes resource deposits, landmarks, city sites, and special opportunities before you commit to expansion.

City specialization and adjacency planning

Founding a city is only the beginning. Each settlement has a limited building layout where adjacency bonuses, population, local climate, and available slots determine its role. A city can become a production center, research hub, food supplier, support generator, or specialized terraforming base, but trying to make every settlement do everything usually wastes valuable space.

Regional buildings extend your influence beyond the city grid, while city buildings create the main production engine. Placement matters because several structures become stronger when positioned near the right neighbors. The result is a compact optimization puzzle inside the wider colony strategy, rewarding players who plan a city several projects ahead instead of filling empty spaces immediately.

Leaders add another layer of flexibility. You choose between candidates with different active skills and passive specializations, then replace them as their terms end. A leader may improve exploration, production, trade, terraforming, or population management, so leadership choices can redirect an entire campaign rather than simply provide a small statistical bonus.

Terraforming is a strategic economy

The end goal is not merely to place buildings. You must raise Mars' global temperature, oxygen, and rain levels while managing the planet's ocean development. These parameters improve local living conditions and help the colony satisfy increasingly demanding population expectations.

Terraforming also changes the map. As oceans rise, low-lying locations can flood, forcing you to anticipate future geography instead of treating every tile as permanent. Dikes, relocation tools, height differences, and city planning become part of the long-term puzzle. A productive site today may become a liability if its position conflicts with later planetary changes.

Lifeforms provide another route to progress. You can import and spread bacteria, plants, and animals, each offering benefits such as food, science, support, oxygen, or temperature improvements. Their value increases when you plan where and when to introduce them, since spreading life is both a terraforming decision and a way to strengthen the colony economy.

Scenarios, custom rules, and weekly challenges

Terraformers is structured around replayable scenarios rather than a conventional linear campaign. Scenarios use different victory conditions and difficulty levels, with Mastery Levels rewarding faster or more demanding completions. This gives experienced players a reason to revisit familiar objectives with tighter planning.

Custom Mode lets you adjust the victory goal, expectation growth, and environmental harshness. You can create a more relaxed colony, increase the pressure from damage events, or remove the victory target for an open-ended sandbox-style run. Shared seeds also allow players to compare results on the same planet, project order, and event sequence.

The game includes a Weekly Challenge mode with rotating modifiers and multiple difficulty levels. This is a strong fit for players who enjoy score attacks and repeatable strategy puzzles more than a single fixed story. The mastery loop is closer to improving a board-game solution than building one permanent empire.

Base game and DLC content

The paid base game contains the main Mars colonization systems, scenario structure, procedural planets, leaders, exploration tools, lifeforms, trade, and space projects. It is a single-player experience, and the commercial model is a traditional premium purchase rather than free-to-play or an in-game shop.

The current DLC lineup contains three gameplay expansions plus a cosmetic Supporter Pack. New Frontiers adds outposts on other celestial bodies, including Venus, Jupiter, and Saturn, with new expeditions, events, leaders, projects, and a longer scenario. Megastructures introduces ten researchable megastructure designs that can be upgraded and integrated into Martian cities.

Independence adds competing Martian factions: Scientists, Industrialists, and Humanists. You must balance their influence because allowing one faction to dominate can push the colony toward autocracy. The Terraformers Collection bundles the base game with New Frontiers, Megastructures, and Independence, while the Supporter Pack focuses on artwork, an artbook, and music rather than new mechanics.

Who should play Terraformers?

Terraformers suits players who like turn-based city builders, resource puzzles, procedural maps, and strategic games where every project choice has an opportunity cost. It is particularly rewarding if you enjoy studying production chains, planning building adjacency, and replaying scenarios to improve your mastery level.

It is less suitable for players looking for real-time colony simulation, direct combat, multiplayer, character-driven storytelling, or unrestricted construction. The card-based project flow means you must work with the options presented to you. That uncertainty is central to the design, not a temporary restriction that disappears after research.

Players who want a more continuous Mars settlement simulation may prefer large-scale sci-fi colony builders such as Surviving Mars Relaunched, while Terraformers is the tighter and more abstract choice for turn-by-turn optimization.

PC features, controls, and localization

The PC version supports keyboard and mouse controls as well as full controller support. Steam also lists Steam Deck-oriented controller icons and interface support, making the game practical for handheld strategy sessions. The design remains menu-heavy and map-focused, so mouse input is still the most direct way to manage dense project and city screens.

Terraformers supports Steam features including achievements, Steam Cloud, trading cards, stats, and Family Sharing. The Steam edition uses the Steam client, while the GOG edition is advertised as DRM-free and can be installed and played without GOG Galaxy or a permanent online connection.

The official text localization covers English, French, German, Spanish from Spain, Russian, Simplified Chinese, Polish, Korean, and Japanese. Full audio is not listed as a separate supported feature on the storefront; the localization is focused on interface and subtitle text.

Ultrawide users should set expectations carefully. The game offers resolution settings and later updates addressed some display issues, but developer discussions indicate that very wide formats may still show side bars rather than a fully expanded ultrawide presentation.

Similar games and buying questions

Terraformers shares its replayable settlement structure with roguelike city builders like Against the Storm, although Terraformers replaces real-time seasonal pressure with deliberate turns, project drafting, and planetary terraforming. Its closest thematic comparison on the site is Mars-focused strategy games such as Per Aspera, but Terraformers is more scenario-driven and less concerned with continuous industrial automation.

These comparisons highlight the game's identity: it is not simply a Mars city builder. It is a solo strategy puzzle about using incomplete information, limited actions, and changing planetary conditions to create a colony that can meet its next demand.
