Features

Browse GameBanana

Search the Deadlock catalog and install mods without leaving the app. Archives are extracted for you, and 1-Click Install links on GameBanana open in Grimoire.

Installing mods

Browse view: mod cards with like and view counts and an Install button on each

Load order and conflicts

Enable, disable and reorder your mods. Grimoire warns you when two mods replace the same game files.

Load order Conflicts

Installed view: enabled mods numbered in load order, each with a toggle

Hero Locker

Keep every skin you download and choose one per hero. The others stay installed, so switching takes a click.

The Locker

Celeste's locker page listing five installed skins

Cursors, HUDs and more

Cosmetics that aren't tied to a hero get their own categories: soul containers, cursors, HUDs, announcers, killstreak music.

General cosmetics

The General shelf: categories on the left, cursor sets on the right

Installer
The usual pick.
Portable
A single executable, the same app as the installer. No install step.

Experimental

Apple Silicon only. Deadlock has no Mac build, so it needs to run in a CrossOver bottle. The app isn't signed, so macOS asks you to confirm the first launch.
