There are a lot of problems with this, one being spawn camping. even if you set a random amount of spawns all over the arena people are still limited to spawning there. It would essentially be who ever gets there first and finds the spawns wins.
If the host was playing he couldn't be banned, so the host would win all the time.
Or film it. :)
Make the maze very tall, and have a few ways to get up where the 2nd floor would be really high up so that you wouldn't be able to see below (consider this is a dark map though) + Where if you fell down you would die.
Does the ban-hammer allow non-admins to ban?
I would appreciate Kickhammer DM even more. c:
