Sol One Early Access: What's in the Launch Build and What Isn't

Sol One launches into Steam Early Access on November 13, 2026. What the EA build includes, what is promised, and what to expect from it.

Last Updated: 2026-11-10

Sol One is not launching as a finished game. It arrives on November 13, 2026 as a Steam Early Access title, and the developer has been unusually specific about what that means: a complete survival loop, a tier-one research tree, and a long list of systems that will be expanded after launch.

This page is a buyer's guide to that build. It separates what is in, what is planned, and what nobody knows yet.

What Early Access includes

The developer's pre-launch material describes the launch build as containing:

  • The full survival loop. Oxygen, power, water, food and the interconnect between them.
  • Base building with indoor pressurization. Sealed habitats, airlocks, and life support that depends on the seal.
  • A tier-one research tree. A research bench, samples and data points that unlock technology.
  • The science system. Collecting and studying samples, with data points as a research currency.
  • Points of interest. Crashed ships, earlier landing sites and abandoned mission bases, with salvage and story.
  • Vehicles. The Crawler ground vehicle and autonomous rovers for scouting and hauling.
  • Crafting at three tiers. Extraction, processing and fabrication.
  • The rocket. The route home and the game's stated goal.
  • A reworked UI and main menu, plus options.

That is a substantial feature list for a solo-developed Early Access launch. It is also the ceiling of what is confirmed; anything not on the list should be treated as unannounced.

"Complete survival loop" is the key phrase

It means the game is playable end to end in the sense that you can survive, build, research and pursue the rocket. It does not mean the content volume of a finished game.

What Early Access does not include

No dated roadmap has been published. The developer has discussed Early Access in general terms, and the store page will carry the standard EA description, but there is no public list of update dates.

What that means practically:

  • No promised update cadence. Do not buy on the assumption of monthly content drops.
  • No confirmed 1.0 date. Early Access durations vary wildly; there is no announced exit date.
  • No confirmed feature list beyond launch. Additional biomes, vehicles, story and research tiers are plausible, not promised.
  • No mod support announced.
  • No multiplayer announced. The game is single player.

Why the game was delayed

Sol One was originally expected in August 2026. The developer delayed it, published an apology, and explained the delay in detail: the terrain had been rebuilt from scratch as an infinite procedural Mars, the construction system had been reworked, and the game needed more time.

The delay is the best available signal about the Early Access build's quality:

  • The developer chose to rebuild foundations rather than ship the older versions.
  • The added systems — pressurization, life signs, suit handling, vehicles, science — are exactly the systems an Early Access survival game needs to be worth playing.
  • A rebuilt foundation is also a less-tested one. Expect bugs, balance swings and save-breaking changes.
Early Access and saves

Treat every major update as a possible save break. Keep a manual backup of a run you care about, and do not start a "forever" save until the game's update pattern is clear.

How to judge an Early Access purchase

A simple framework:

Buy now if:

  • You want to learn the systems while the community is small and the guides are being written.
  • You are comfortable with the game changing under you.
  • You want to support a solo developer building an ambitious survival game.
  • You enjoy the early phase of a survival game more than the finished one.

Wait if:

  • You want a polished, complete campaign.
  • You need controller or console support.
  • You are sensitive to bugs, balance changes or save wipes.
  • You want to see whether the rocket path and the late game hold up.

The price question

No price has been announced. Early Access titles commonly launch at a discount relative to the eventual 1.0 price, but that is a pattern, not a promise. The price page→ tracks what is known; at the time of writing, the honest answer is "not announced."

What to play first

If you buy at launch, the first session should be about the survival loop, not the rocket:

  1. Land, read the HUD, find your first ice and ore.
  2. Build a small sealed shelter with an airlock and a life-support chain.
  3. Stabilise power before you expand.
  4. Start research as soon as the bench is up; samples are the long pole.
  5. Build the Crawler when the base can spare the fabrication time.

The beginner guide→ covers that first day in detail.

Early Access versus a full release

Worth stating plainly, because the store page will not: Early Access is a funding and feedback model, not a demo. You are buying the current build and the developer's intention to improve it. Sometimes that works brilliantly; sometimes the game stalls.

The signals here are mixed but mostly positive: a solo developer with a clear vision, a substantial launch feature list, a delay spent on foundations rather than marketing, and a demo that reportedly took wishlists from 5,000 to over 25,000. The risk is the normal EA risk: the late game may be thin, and the update pace is unknown.

What to watch after launch

  • Patch notes for save compatibility and balance.
  • The store page's EA description, which the developer is expected to keep current.
  • Community reports on the rocket path and the late game, which are the parts hardest to judge from marketing.
  • The demo question — see the demo page→ for what is known.
