OpenCAGE

OpenCAGE is an open source modding toolkit for Alien: Isolation, powered by CathodeLib, which allows access to a range of configurations and content through a graphical interface.

PLEASE NOTE: OpenCAGE is now only distributed via Steam!

  After downloading, launch OpenCAGE and locate Alien: Isolation's AI.exe if requested.

  Once the toolkit has set itself up you will be prompted to load a level into the editor. After loading you can browse all of the level's scripts (called Composites) within the main window to modify the logic. From the toolbar at the top you will find the ability to launch into the game, manage backups, and modify a variety of configurations for characters, items, and more. In the toolbar you can also find tools to edit behaviour trees and assets (models, textures, materials, and more) within the loaded level, or globally across the game.

  Documentation can be found on the OpenCAGE website for most functionality within the toolkit.

  If there is a section missing from the docs currently that you'd like to see added, feel free to open an issue on GitHub and it will be prioritised. Additionally, join the Discord to get direct help from the community!

  Please note: bug reports should be directed to the GitHub page, where they will be reviewed and actioned appropriately.
