A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Today's patch fixes a few issues that some players have reported: Fixed crash on startup when using FSR on some GPUs Fixed crash when completing some Adventures Fixed being able to take damage while still in the loading screen (and then getting stuck in loading) Thanks for your bug reports! Use the in-game bug reporter where possible to report issues.
Greetings Gremlins!Today we’re happy to share with you what we’ve been working on for the last few months since launching Mother Machine: a demo of an experimental new game mode, which we’re calling Co-Op Gremlin Tours!In Co-Op Gremlin Tours, you and your Gremlin friends are on a trip to the (newly terraformed) surface of the planet, using the drilling machines left behind by the Creators. Each Tour will take you through a number of small caves, each with its own distinct theme and goal. At the end of each cave, you will find another drill taking you to the next cave: but first, you and your G
Greetings Gremlins, Today's update brings a long-requested feature to the game: Offline Mode! There's also support for AMD's FSR technologies to get a faster frame-rate, a new Leg-Up ability, and more - here are the full details: Offline Mode: You can now play Mother Machine without an internet connection! If you want to force the game to always play offline, there's a new option in the game settings. And if you can't connect to the shared Mother's Home but otherwise are online, you can still play the game and join your friends in the Caves as normal. Leg-Up Ability: Hold the Climb button with
Our Gremlin technicians have been very busy in the last few weeks and we are happy to announce that Mother Machine is now officially Steam Deck Verified.

In the meantime, let us know about your experience on the Steam Deck with Mother Machine!

Greetings Gremlins! Today's update adds support for DLSS technologies and also gives you more control over how some of the graphics options behave. We know many of you woud like the game to run at a higher frame-rate, and this is just the first step to making that happen. We are focusing on optimizing the game, both in terms of rendering performance and also the overhead of managing everything that's going on in the cave for devices with less powerful CPUs (looking at you, Steam Deck!). There are also a few tuning changes and of course bug fixes in this update. We've seen that the platform nex
