Signs of Life Game Guide: 1.0 Survival, Crafting and Co-op

A complete Signs of Life guide for 1.0: first-hour route, base building, crafting, co-op, Xenoid story and the post-game colony.

Signs of Life is not a hardware showcase. It is a pixel-art sandbox with procedural worlds, and its listed requirements are deliberately modest. That does not mean every machine will run a large colony smoothly, but it does mean you probably do not need an upgrade to try it.

A modest machine can run the game; the settings matter more.

Official minimum requirements

The Steam store lists the following for Windows:

• OS: Windows 10
• Processor: dual-core 2.0 GHz
• Memory: 2 GB RAM
• Graphics: OpenGL 3.0 capable
• Storage: 1 GB available space

The recommended memory is 4 GB RAM. The store does not list a specific GPU model, which is unusual but consistent with the game's OpenGL renderer. If your GPU supports OpenGL 3.0, it is probably enough to launch.

Linux support

Signs of Life ships with a Linux build. The store's system requirements are listed for Windows, and the Linux build uses the same OpenGL renderer. If you are on Linux, make sure your graphics driver exposes a modern OpenGL context; Mesa drivers on Intel and AMD hardware generally do.

The game is not Steam Deck Verified as of this writing. That does not mean it will not run, but do not buy it expecting a verified handheld experience.

What actually affects performance

The listed requirements tell you whether the game will start. They do not tell you whether a 40-hour colony will run well. The variables that matter most are:

World size

New characters can choose Small, Medium or Large worlds. A smaller world generates fewer chunks and reduces the amount of terrain the game has to track. If you are on a low-end laptop, choose Small. You can still reach every story location; the world is dense rather than empty.

Colony size

The post-game colony adds colonists, rooms, jobs and Pneumail storage. A large colony with many active rooms is heavier than a solo base. If performance drops after you start recruiting colonists, reduce the number of active rooms or assign fewer simultaneous jobs.

Co-op hosting

The host does the simulation work. If you are the host, your machine is also the server. A player who can run the game solo may still feel input delay when hosting three friends on a large world. For co-op, choose a smaller world and a host with the best single-core performance.

Background applications

The game is not demanding, but it is a sandbox that benefits from RAM. Close browser tabs before a long building session on a 4 GB machine. On 8 GB or more, this is rarely an issue.

How to improve performance

1. Lower the world size at character creation. This is the biggest single lever and cannot be changed later without a new world.
2. Separate world scale and UI scale. 1.0 split these settings. Lower the world scale before lowering the UI scale; the interface is harder to read when shrunk.
3. Reduce the number of lights and active machines. Large rooms with many lights and stations cost more than empty rooms.
4. Host co-op on the strongest machine. The host is the server, so a weak host makes everyone lag.
5. Update graphics drivers. OpenGL 3.0 is old, but drivers still matter for stability.
6. Verify game files after a crash. Steam's file verification fixes most launch failures caused by partial updates.

What to do if the game will not launch

• Check that your GPU supports OpenGL 3.0. Integrated graphics from before 2010 may not.
• Update the driver. On Windows, use the vendor's tool rather than Windows Update.
• Launch the game once without mods. A broken mod is the most common cause of a black screen after the logo.
• Check the game's install folder for a crash log. The Steam community forums are the fastest place to compare logs with other players.
• On Linux, check that your Mesa or proprietary driver is installed and that glxinfo reports an OpenGL 3.0 context.

Is 2 GB RAM enough?

For a small world and a solo base, yes. For a medium world with a large base, co-op and a browser open in the background, no. 4 GB is the realistic floor for comfortable play, and 8 GB gives you room for Discord and a browser.

The game's minimum is honest, but minimum is not the same as comfortable. If you are buying a used office PC for this game, check that it has at least 4 GB and a CPU with two real cores rather than two threads.

Does the game support cloud saves?

Yes. Steam Cloud is listed on the store page. Cloud sync is convenient for moving between machines, but it can also overwrite a local save if two machines disagree. Before a long session, close the game on the other machine and let Steam finish syncing.

For co-op hosts, the world save lives on the host's machine. Cloud saves do not turn a host into a dedicated server; if the host is offline, nobody can join.

Should you buy the Steam version?

Yes, if you want the simplest install and automatic updates. The official site links to Steam, and the game is not sold as a separate standalone build. The Steam version also gives you the Workshop and mod support that ships with 1.0.

FAQ

Can my laptop run Signs of Life?

If it has a dual-core 2 GHz CPU, 2 GB of RAM and OpenGL 3.0 support, it should launch. For comfortable play, 4 GB of RAM and a small world are recommended.

Does Signs of Life run on Linux?

Yes, a Linux build is available on Steam. You need a driver with OpenGL 3.0 support.

Is 1 GB of storage accurate?

The store lists 1 GB available space. Updates and saves add to that, so leave a little headroom.

Is Signs of Life on Steam Deck?

It is not Steam Deck Verified as of 10 November 2026. It may run through Proton, but that is not an officially supported guarantee.
