It will be a completely different map, when you load a world you will be able to choose which save file/world you want to load. Alternatively if you play on Official servers then there will be new servers to run the new map
This would be nice alongside the ability to remote use entire stacks, force feeding a Giga or high health creature is giving my XB1 controller a squeak lol
You are always the bearer of such amazing news Jer! Thank-you so much for clarifying these points, super excited to run The Centre on my player dedicated!
