Surviving Mars: Colony Survival Guide

How to land, expand, and keep colonists alive in Surviving Mars: opening build order, resource chains, disasters, mysteries, and the status of the original game versus Surviving Mars: Relaunched.

Researched September 2026 — current as of the original game's final build (Martian Express era, 2022) and Surviving Mars: Relaunched updates through September 2026. Live games change; check the linked sources if something differs.

Status note: The original Surviving Mars (Steam app 464920) is no longer sold on the Steam store as of September 2026. Paradox replaced it with Surviving Mars: Relaunched, released November 10, 2025 on PC, PS5, and Xbox Series X/S, which bundles the base game and previous expansions with upgraded visuals, a refined UI, and the new Martian Assembly political system. If you already own the original, it stays in your library and remains fully playable offline. Everything in this guide applies to both versions unless flagged.

Quick Start

• Start on an easy sponsor. International Mars Mission has the most funding and the most forgiving perks. Save the hard sponsors (Church of the New Ark, Paradox) for later runs.
• Pick a landing site with concrete, metals, and water close together. The pre-landing screen shows resource and disaster ratings; a site with low disaster threat and nearby deposits is worth more than anything else.
• Build power, water, and oxygen before your first dome. Colonists need all three from the moment they arrive.
• Don't rush colonists. Get a Drone Hub network, Concrete Extractor, water, oxygen, and a food source running first. Colonists arriving to a half-built dome die fast.
• Keep reserves. Water tanks, oxygen tanks, and batteries turn a disaster from a colony-ending event into a nuisance.
• Scan and explore anomalies. The RC Explorer investigates anomalies for research boosts, resources, and breakthroughs. Breakthroughs are some of the strongest upgrades in the game.
• Export Rare Metals for funding. Rare Metals can be sent back to Earth for cash, which funds rockets and supplies.
• Plan for maintenance. Every building collects dust and needs repair resources; your drones need spare metals, concrete, polymers, and machine parts on hand.
• Use cables and pipes carefully. One broken pipe or cable can take out an entire dome's supply. Build redundancy.

Before You Land: Setup Choices

Mission Sponsors

Sponsors set your starting funds, rocket count, and unique perks. Relaunched values shown; the original game's list is similar but excludes the Interplanetary Codex.

Sponsor | Difficulty bonus | Standout perk

International Mars Mission | 0% | Most starting funds; colonists never get Earthsick; rockets self-refuel

USA | +40% | Regular funding income; Mega Mall

Blue Sun Corporation | +50% | Cheap applicants and rockets; orbital scans reveal deep deposits

China | +60% | Passenger rockets carry extra colonists; applicants appear faster

India | +90% | All building costs reduced

Brazil | +100% | Colonists grant funding on arrival

Terraforming Initiative | +100% | Boost to terraforming techs

Europe | +110% | Funding for each tech researched

SpaceY | +130% | Stronger Drone Hubs; advanced resources cheaper from Earth

Church of the New Ark | +170% | Doubled birth rate; all colonists religious

Japan | +170% | Cheaper rovers; better specialists

Russia | +180% | Cheaper fuel refinery prefabs; free fueled extractor upgrades

Paradox Interactive | +200% | Extra breakthroughs; very little money

Interplanetary Codex (Relaunched pass) | 0% | Starts with Martian Assembly and Earth Embassy prefabs; unique Law Office building

Commander Profiles

Commander profiles add a smaller bonus (a pre-researched tech, a production boost, or a unique perk). For first runs, read the tooltips and pick one that shores up your sponsor's weakness: extra money for low-funding sponsors, or a production/research boost for rich ones. Harder profiles raise your difficulty score.

Landing Site

• Check resource deposits (Concrete, Metals, Water, Rare Metals) and threat ratings for Dust Devils, Dust Storms, Meteors, and Cold Waves.
• A flat site near multiple deposits is ideal.
• Higher threat equals higher difficulty score but more disasters.

Resources and Production Chains

Resource | Where it comes from | Used for

Concrete | Concrete Extractor on concrete deposits | Almost every building

Metals | Surface deposits (drones), Metals Extractor | Buildings, repairs

Rare Metals | Rare Metals Extractor | Export for funding, advanced buildings

Water | Water Extractor (deposits), Moisture Vaporator | Colonists, farms, some factories

Oxygen | MOXIE | Colonist survival

Power | Wind Turbine, Solar Panel, Stirling Generator, later Fusion | Everything

Food | Hydroponic Farm, Farm (inside domes) | Colonists

Polymers | Polymer Factory (Water + Fuel) | Advanced buildings, repairs

Machine Parts | Machine Parts Factory (Metals) | Advanced buildings, repairs

Electronics | Electronics Factory (Rare Metals) | Research and advanced buildings

Fuel | Fuel Refinery (Water) | Rocket refuelling, Polymers

Rule of thumb: import advanced resources (Polymers, Machine Parts, Electronics) from Earth early, then build local production once you have workers.

Opening Build Order (Relaxed Start)

• Drone Hub placed centrally near deposits, with drones.
• Concrete Extractor on the nearest concrete deposit.
• Power: Wind Turbines (steady, day and night) plus a couple of Solar Panels, and a Power Accumulator (battery).
• Water: Water Extractor on a deposit, or a Moisture Vaporator if there are no deposits close by; add a Water Tower.
• Oxygen: MOXIE plus an Oxygen Tank.
• Second Drone Hub near a Metals deposit.
• Fuel Refinery so your rockets can return to Earth.
• First Dome: a Basic Dome with a Living Complex, Hydroponic Farm, and a service building (Grocer or Diner).
• Founders: bring your first colonists only when the dome has water, oxygen, and power flowing with backups. Your first batch of colonists (the Founders) has to survive a set number of Sols before new applicants arrive.

Colonists and Domes

Colonist Stats

• Health: drops without oxygen, water, food, or medical services.
• Sanity: drops from disasters, working in unpleasant conditions, and bad shifts.
• Comfort: from housing and services.
• Morale: combines the other stats plus traits.

Specializations

Engineer, Scientist, Geologist, Botanist, Medic, Security (and unspecialised colonists). Match specialists to workplaces for a big efficiency bonus: Geologists in extractors, Botanists in farms, Scientists in research buildings, Engineers in factories.

Dome Tips

• Keep work and home in the same dome or connect domes with Passages so colonists don't commute across the map.
• Filter domes by specialization in the dome filter panel to avoid mismatches.
• Build services that fit your population: Grocer, Diner, Infirmary, Spacebar, Medical Center, Garden.
• Use the Sanatorium and School (from research) to remove bad traits and add good ones.

Research and Breakthroughs

• Research is split into fields: Biotech, Engineering, Physics, Robotics, and Social.
• Early priorities: anything that improves drones and extractors, farming tech for food, and the techs that unlock larger domes and factory production.
• Breakthroughs appear from anomalies and are random each run. Standouts include Artificial Muscles, Superconductive Materials, and Hive Mind.
• In Relaunched, the free update released on September 8, 2026 (alongside the Feeding the Future content pack) rebuilt two of the game's core systems. Check the in-game patch notes: tech names and positions may differ from older guides.

Disasters

Disaster | Effect | How to prepare

Dust Storm | Reduces solar output, halts some extractors and MOXIE output, adds dust | Stockpile oxygen and water, use Wind and Stirling power

Cold Wave | Freezes water, raises power demand | Store power and water, build Subsurface Heaters

Meteor Storm | Damages buildings and cables | Keep repair resources; later build MDS Lasers

Dust Devils | Coat nearby buildings in dust, speeding up maintenance needs | Keep drones and repair resources close

Always keep a reserve of oxygen, water, and power storage equal to a few Sols of demand.

Mysteries

Each run can include a Mystery with its own storyline, choices, and rewards. Difficulty varies:

Mystery | Difficulty

The Power of Three | Easy

Inner Light | Easy

Beyond Earth | Easy

The Philosopher's Stone | Easy

The Dredgers | Medium

Artificial Intelligence | Medium

Spheres | Medium

St. Elmo's Fire | Medium

The Last War | Hard

Wildfire | Hard

Marsgate | Hard

Metatron | Hard

Asteroid mysteries also exist with the Below and Beyond content.

Expansions and Updates

• Green Planet: terraforming, plants, and atmosphere goals.
• Space Race: rival colonies and diplomacy.
• Below and Beyond: underground and asteroid mining.
• Martian Express: trains (2022).
• Relaunched additions: Martian Assembly political system (with a possible route to independence from Earth), reworked asteroids (they no longer expire, have more buildable ground, dedicated Metals/Rare Metals/Exotic Minerals Micro-G extractors, and rockets can fly directly between Earth, Mars, and asteroids), a reworked Underground based on player feedback, and the September 8, 2026 free update that rebuilt two core systems. The first part of the Prime Mission expansion pass, Feeding the Future (released September 8, 2026), adds deeper food and production management with new ingredients and meals; Machine Utopia is announced as the later expansion.

Common Mistakes to Avoid

• Bringing colonists too early. Always have oxygen, water, food, and power buffered.
• One cable or pipe path. A single meteor can break your supply; build loops and backups.
• Too few drones. Drone Hubs get overloaded; add drones or a second hub when resources pile up.
• Neglecting maintenance. Buildings break down; keep repair resources stocked near hubs.
• Mixing specialists randomly. Mismatched jobs tank productivity.
• Ignoring Earthsick colonists. They'll try to leave; build services to keep them happy.

Advanced Tips

• Rare Metals exports are your money engine. Automate Rare Metals extraction early.
• Upgrade extractors with Amplify and Automation upgrades after researching them.
• Use Shuttles (after research) to move resources between hubs automatically.
• Food is the long game: once you have Botanists, large in-dome Farms scale better than a pile of Hydroponic Farms. Watch soil quality and rotate crops.
• Tourism and Wonders: Build Wonders (such as the Space Elevator) to change your economy.
• Specialization domes: Build domes around work types (farming domes, research domes).
