Umurangi Generation: How to Get “Speed runner”

The “Speed runner” achievement is broken for a lot of people. This seems to be a bug with one of the more recent patches. This guide will show you how to use Steam to download and run an older version of Umurangi Generation.


The Speed runner achievement appears to be broken for many people, myself included. This appears to be an issue introduced with the updates published in 2022. Fortunately, Steam allows users to download earlier versions of the game, ones in which the achievement isn’t bugged, that we can use to unlock it!

It’s at this point I must say I’m indebted to StepS’s guide on downgrading Beat Saber, without which I would have never known that this sort of thing was possible. That guide has additional reading into this sort of technique, so please check it out if you’re interested in learning more.

1) Determining The Codes Needed to Download

In order to use Steam to download the specific version of Umurangi Generation we want we are going to need three codes: the App ID, the Depot ID, and the Manifest ID. We can look up all of these using SteamDB.[]

The App ID for Umurangi Generation is 1223500. The Depot ID is 1223501. However, the Manifest ID is different for each version, and this is what we’ll use to download the specific version we want. I mentioned earlier that the bug appears to be introduced in the 2022 updates, possibly the June update but I’m not 100% sure. To be safe, I chose the 2021-Oct-12 update, which has a Manifest ID of 5540599311058635572

2) Using the Steam Console

Press Win + R to bring up the Run prompt. Input steam://open/console and run it.

Steam should switch to a console section with an entry field at the bottom. The format we use is “download_depot <App ID> <Depot ID> <Manifest ID>”. So for the 2021-Oct-21 version the code is “download_depot 1223500 1223501 5540599311058635572

Press Enter to begin your download. Steam will not display download progress, but it should be running the the background. Wait until you see the message that begins with “Depot download complete”.
Take note of the file path, you’ll be using it shortly.

3) Managing Files

Open up your file directory, find your Steam Library and then go to steamapps->common->Umurangi Generation. There should be another Umurangi Generation folder in here. These are your game files. I recommend backing them up somewhere if you don’t want to re-download the game once you’re done with this whole affair, but either way, remove it entirely. We don’t want any conflicts or weird behaviors due to “mixing” this current version with the old version.

Now go to where you downloaded the old version. You can copy the address you received from your Steam Console and paste into the address bar of your file explorer. Once you are there, move everything into your steamapps\common\Umurangi Generation folder.

Congratulations, you have downgraded your game. In your Steam program go back to your library and play your game like normal. Re-earn the Speed runner achievement, and once you are finished with this version of the game, either replace your game files with your back-up, or have Steam re-download the current version to restore everything to normal.
