OpenCAGE is a community-created modding toolkit for Alien: Isolation which enables custom scripting, configuration, and content modification through graphical user interfaces.

This powerful tookit opens up a whole world of possibilities including custom models, missions, weapons, behaviours, and maps – with more functionality being added and improved over time!
