BepInEx-BepInExPack_Core_Keeper-2.1.0 icon

BepInEx pack for Core Keeper. Preconfigured and includes Unity Base DLLs.

Preferred version: 2.1.0


CoreKeeper Ultra-wide Fix


  • Removes pillar boxing in the menus.
  • Expands viewport width. Note you will see world spawn/de-spawning near the edges of the screen. Most likely be worse the wider the aspect ratio.
  • The viewport width is adjusted automatically, but a custom width can be set.
  • Press F1 to bring up the configuration window in game. Only needed if you want to change the width manually - it defaults to your aspect ratio by default.

(The menu has some quirks grabbing the mouse, works best when paused.)



  • This uses a custom build of BepInEx from here should it need updating in the future.
  • The game is also an IL2CPP game, so first start (and after any game updates) will be a little longer while it generates assemblies.


Manual Installation

  • Install BepInExPack_Core_Keeper first.
  • Extract the contents of the release zip in to the game directory.
    (e.g. "steamapps\common\CoreKeeper" for Steam).
