Sol One Tips: 20 Things I Wish I Knew Before Landing
Practical Sol One tips for the first week: oxygen discipline, base pressure, power margins, research order, rover logistics and the mistakes that end runs.
Most Sol One runs do not end in a dramatic disaster. They end in a slow cascade: a small oxygen leak, a battery that never quite recharged, a field trip that came back after dark, a base that was always one repair behind. The tips below are the habits that prevent the cascade.
They are ordered by when they matter, not by importance. The first ten apply from hour one.
First hour
1. Read the HUD before you move. Oxygen, suit tank, health, hunger, thirst and rest are all on screen. Knowing which bar is falling is the whole early game.
2. Build the smallest sealed room that works. One room, one airlock, one life-support chain. A small volume is cheaper to pressurize, heat and fill with oxygen.
3. Do not take the helmet off until the room reads breathable. The suit is your backup life-support system. A sealed room that is not yet pressurized is not a reason to remove it.
4. Find ice before you need it. Water is the resource that gates everything else. The first expedition should locate an ice deposit and mark it.
5. Put the base between the ice and the ore. Location is a permanent decision made in hour one. A base beside the ice but an hour from iron is a bad trade.
6. Craft the oxygen reserve before the second room. Every new pressurized volume is a new demand on the producer. Add reserve first, rooms second.
Before every trip outside, spend five minutes: fill the tank, fill the water, check the battery, check the weather, decide the return trigger. Five minutes saves hours.
First day
7. Power margin is not optional. Size generation for the night plus a storm, not for the best-case noon. A base running at 95 percent is a base one cloud away from failure.
8. Separate critical loads. Oxygen and heat must not share a circuit with the fabricator. If a build lets you prioritise, prioritise; if not, manage it manually.
9. Build storage before you build comfort. Material on the floor is material you will lose track of. Containers are cheap and they pay for themselves in saved trips.
10. Start research early. Samples are the long pole. Every field trip should come back with something to study, even if it is not the material you needed.
11. Keep seed stock. If a crop can be eaten or replanted, plant the first harvest and eat the second. Eating your seed corn is a classic first-week failure.
12. Do not expand during a good day. Expand during a stable day — power full, water full, food positive. Good weather is for field trips.
First week
13. Build the Crawler before the second outpost. The vehicle changes the logistics math. A forward camp without transport is a cabin you walk to.
14. Put a beacon at the base. Low visibility is the normal condition during storms, and "the base is that way" is not a navigation system.
15. Batch your fabrication. Running the fabricator for one part at a time wastes power and time. Queue a session's worth of parts.
16. Stock rocket material separately. One container, never touched for base repairs. The project survives on discipline.
17. Do not chase every POI. Points of interest are tempting and expensive. Go when you have cargo space and a reason, not because the marker is there.
18. Repair before you upgrade. A sealed room with a failing airlock is a liability. Fix the seal, then add the room.
19. Watch the day-night cycle. Night is cold and dark. Plan field trips to return with an hour of daylight in hand.
20. Keep a manual save. Early Access builds change. A save you can return to is worth more than an hour of progress.
The mistakes that end runs
Four failure patterns, in order of frequency:
The oxygen cascade. A leak or an overloaded producer drops the habitat atmosphere, the player panics, cycles the airlock repeatedly, and loses more atmosphere each time. Fix: reserve oxygen, and treat the airlock as a scarce resource.
The power spiral. Fabrication runs through the night, the battery empties, oxygen production stops, and the base is cold and breathless by morning. Fix: critical loads on their own circuit and a hard rule against fabricating on a low battery.
The field trip overrun. A short trip becomes a long one, the suit tank runs low, and the walk home is longer than the reserve. Fix: a return trigger set before departure, and a spare tank in the rover.
The rocket rush. The player starts the rocket before the base is stable, diverting power and material, and the habitat degrades while the project stalls. Fix: the readiness checklist in the rocket guide→.
Every one of those failures gets worse when the player rushes. The game rewards a pause: stop, read the HUD, decide, then act. The pause is the skill.
Efficiency tips
- Mine in batches. One trip for iron, one for copper, one for ice. Switching targets mid-trip wastes the trip.
- Process while you sleep. If the build allows it, queue processing overnight; it is the load the base can carry while you are idle.
- Build a suit room. A small pressurized room at the airlock where you change tanks keeps dust out of the habitat and saves oxygen.
- Use the rover as a depot. Park it at the dig site with water, a spare tank and a container. It is a forward base on wheels.
- Keep a written plan. Next unlock, next build, next trip. Three lines.
What not to bother with early
- Decorative building. The game rewards function first. Beautify after the rocket.
- A second outpost before the Crawler. You cannot supply two bases on foot.
- Deep research branches. Tier one is enough until the base is stable.
- Long POI expeditions. The story will still be there when you have cargo space.
FAQ
What is the most important tip for new players? Build small, seal it, and do not take the helmet off until the room is breathable. The opening is a pressure problem before it is a survival problem.
How do I stop running out of oxygen? Reserve first, rooms second. Keep a spare tank at the airlock and avoid unnecessary airlock cycles.
Should I build solar or a generator first? Whatever the build lets you build first, but plan for a mix. Solar alone fails in storms.
When should I build the rover? When the base can spare the fabrication time and you have a second location worth visiting.
How do I avoid losing a run? Keep a manual save, keep a base reserve, and set a return trigger before every trip.
Is there a wrong way to play? Only rushing. The systems punish impatience more than any enemy.
