1WEEK 1.5.1 on SteamOS

Version 1.5.1 of 1WEEK has been tested on a Lenovo Legion Go S SteamOS Edition, a handheld device that ships with SteamOS preinstalled.

The tests were performed directly on SteamOS, running the Windows version of 1WEEK through Proton.

During testing, the game remained stable and worked correctly with controller input and the main gameplay systems.

Successfully tested

  • Launching the game through Steam.

  • Controller support.

  • Movement and interactions.

  • Inventory and equipment management.

  • Menus and UI.

  • Building and object interaction.

  • Save and load behavior.

  • General gameplay performance.

  • Resolution handling on handheld displays.

Handheld and controller improvements

Version 1.5.1 also includes several small quality-of-life improvements based on handheld testing:

  • The B / Return button now closes the inventory when playing with a gamepad.

  • Tooltip positioning has been improved when using the virtual gamepad cursor.

  • Selected menu buttons are now much easier to identify on smaller displays.

  • Cursor sensitivity settings have been improved, including a wider usable range and persistent settings between sessions.

Resolution selector improvement

Testing on SteamOS also revealed an issue with the resolution selector related to the way some refresh rates are reported through Proton.

This could cause the resolution list to appear empty on certain configurations.

This issue has been fixed in version 1.5.1.

Proton compatibility

1WEEK currently ships as a Windows build, so Proton is required to run the game on SteamOS.

The game has been successfully tested with:

  • Proton Experimental

  • Proton Hotfix

Thank you to everyone playing 1WEEK on handheld devices.

Testing on SteamOS will continue, and any compatibility issues found along the way will be addressed whenever possible.

See you underground.
