Warnings

This game requires a virtual reality headset (see VR support for details).

Moss is a third-person adventure platform game with action and puzzle elements developed and published by Polyarc. The game is played from first-person perspective, where the player character can interact with the game world directly using motion controllers, solving environmental puzzles while also control the protagonist with button controls and platforming, resulting in "second-person" gameplay.

Originally released for PlayStation VR on February 27, 2018, Moss launched on Steam and Oculus on June 7, 2018.[Note 1]

The free DLC Twilight Garden was released as an update in June 25, 2019 and is automatically accessible through the levels of the main game. The game has also been updated to support newer headsets and motion controllers, including the Valve Index.

Issues unresolved

CPU usage spikes using Medium or High graphics settings

Set graphics settings to Low[9][10]
Playing on Low is the only way to avoid these spikes
See Anti-aliasing (AA) to modify super-sampling value in order to improve performance or visual quality.

Controls menu option doesn't work

SteamVR enviroment showing every time level is loading

Issues fixed

Incorrect controller instructions and prompts

If the game has trouble determining what controllers are in use, it will fall back on default ones, e.g. with SteamVR it will then show Vive controllers. Even though regular controllers are not supported, game still takes input from them.
Unplug or disable all controllers[11]
  1. If SteamVR is showing controller icon, close SteamVR.
  2. Unplug or disable all traditional game controllers.
  3. Open SteamVR and then launch the game.

Notes

  1. Steam currently incorrectly lists release as February 27th, 2018.
  2. 2.0 2.1 File/folder structure within this directory reflects the path(s) listed for Windows and/or Steam game data (use Wine regedit to access Windows registry paths). Games with Steam Cloud support may store data in ~/.steam/steam/userdata/<user-id>/846470/ in addition to or instead of this directory. The app ID (846470) may differ in some cases. Treat backslashes as forward slashes. See the glossary page for details.

    "We've previously heard from some players that using the left hand for a gamepad and right had for a Vive controller can work. We do allow Gamepad input in addition to VR Controller input. However, we do require a tracked controller for interacting with Quill and the various environments in Moss. I'll clarify that this is not officially supported, but we aren't looking to remove it if players are finding it works."
