The islands could be kinda like little dungeons in the theme of zombie massacre from Gmod Tower, except with swords and flintlocks. at the end, there could be a new upgrade to your weapon, or a huge reward, like an expensive item or 5000 units. I know it would take forever, but since you’re planning to add workshop items, you could maybe add an island editor, and based on votes, you could add them to the world.
these are just my ideas, and will probably end up not being ANYTHING like that
I’m really scared of this one, because since the framerates of the lobby are already awfull and getting worse every update, I wonder what a map expansion would do.
