Would like to know as well. I think bhopping in this game is the best its ever been but I am really missing stuff like bhop_arcane & other "adventure" bhop maps instead of just the short speedrun maps.

I would like to create adventure type maps, especially with all the modern rendering features Unity has to offer. It's on the todo list :)

Keep an eye on the Workshop, community members have been posting maps there

Am keeping a close eye on the game & workshop already ;)
