I believe ASCH’s question was not about private versions. They were asking about the possibility of having multiple active island versions under one code.
ie.
Selecting Battle Royale lets you choose between Battle Royale - Solos/Duos/Squads
As of right now, if we want to split our experiences into Solo/Duo/Squad (or no-build/build) versions we ought to create new island codes, and updating each island’s content to match the other can take a while.
(two versions under same mnemonic mockup)
