I managed to make a Bring Em On! level (fully automated to boot) and it pretty much works, except for the fact only one person can go through a wait tube at a time and players may get stuck in any of the tubes. I took out the No Fire Zones since it was hard enough to kill enemies as it was. Getting hit once basically means you're out, but the game should be easier with more players. I included a timer (which is surprising that I added it since I still loathe Bank Robbery), and there are 9 rounds total.
