Step 1: go to a custom match
Step 2: Scroll down in squads until you see "Void"
Step 3: Make a match using that map
Also, here are some commands.
/gm 1, /gen create global {Item} {gen speed/time} {amount of items allowed at a time}, /bed remove {Id}, /bed create {Color}, /gen remove {id} //pos 1, //pos 2, and //fill {block}
Hope this helps!
