About this project
What does RXB-Kit add?
Massive update! Added a bunch of new blocks and items, with a few extra unique mechanics for survival play too!
As a builder, this mod was originally made to help myself in my creative endeavours making custom maps, but has now been reworked to be survival friendly too, with quite a few interesting gameplay mechanics.
Hope you enjoy, and happy building!
