Olympus - Everest Installer - A Modding Tool for Celeste.

Olympus is an installer for the Everest mod loader and modding API for Celeste, enabling code mods, custom level sets and more.

Linux / macOS users, please follow the instructions on theĀ Everest website.

Windows users, please continue on this page.

Notes:
  • Your system will probably false-flag the patcher as a virus because it modifies Celeste.exe. If you don't trust us, check the source code.
  • If you've previously installed an old Everest installer, you'll need to redownload the newest installer (Olympus) from this page.

Everest is an open-source mod loader and modding API for Celeste, making texture replacements, custom level sets and endless code mods a reality.

Olympus is a tool which lets you download Everest and mods easily, manage your Celeste installation(s) and stay up to date on important Celeste modding news.

Almost all other Celeste mods need you to install Everest first. Likewise, you need other mods to actually do something. Everest only enables other mods.

Take a look at the full feature list on the Everest website.

    Is there a certain beta I'm supposed to be using to open this? Whenever I open it on steam nothing changes. I've been using opengl since without it, the game won't open.

    When I installed the mod, the game started to run slower, with fps drops. Don't know the main reason of that, but also tested in other pcs and I got the same result. (Even in " good" pcs the performance of the game is affected, of course is way way less)

    Thank you for the submit! Any chance we could add 1-click integration, so users can download, extract and install mods right out of the browser?
