The modded client for Cretaceous Isle. One app: it builds a separate, modded copy of The Isle beside your Steam install, keeps it up to date, and leaves your normal game untouched.
Recommended. Installs for your user only, no administrator prompt, and updates itself.
Download for Windows · 94 MBNo installer and nothing written to Program Files - it runs from wherever you put it. It does not update itself, so you will have to come back here for new versions.
Portable .exe · 93 MBThe installer is not code-signed, so Microsoft Defender SmartScreen shows a blue “Windows protected your PC” box. That is the warning for an unrecognised publisher, not a virus report. To continue:
