About this Mod
🧬 What is JS Expanded?
JS Expanded is a complimentary mod for JurassicSaga that adds extra creatures, blocks, and related content from specific franchises that are not part of the Jurassic franchise. The goal is to include stuff that wouldn’t fit the main JurassicSaga mod, while still working alongside it as an optional add-on.
🦖 What does it add?
The mod adds new mobs, blocks, and other gameplay content based on different franchises. Right now this includes things inspired by King Kong (2005), Zoo Tycoon, and other non-Jurassic franchises, with more planned depending on suggestions and what I choose to add.
Some example creatures include:
- Venatosaurus
- Piranhadon
- Moon Spiders
- Bloodfish
⭐ Why download it?
If you want more variety, crossover creatures, and extra building or gameplay content to use with JurassicSaga, this mod is meant to give you that without changing or bloating the main mod. It’s optional, so you only install it if you want the extra stuff.
⚠️ Important info before downloading
- This mod is designed to be used with JurassicSaga and will require it to function properly.
- Content is based on specific franchises and may not be balanced around vanilla or main-mod progression.
- Updates and additions depend on suggestions and development time, so the exact content can change between versions.
