Not sure it was becuase I had set the gravity really high but me (Gotenks007) and my friend (Nightshade) were both goku. We had almost exactly 3.2mil energy and fired a kamehameha wave which stayed right in the middle until our powers ran out. Now mine ran out first so the energy slowly moved towards meand when it blew it killed everyone on the map and I mean everyone. We were on Cell arena large not the desert one. It was unreal so I recommend trying it but it take a while as we were in a struggle for about 2min. I wish I had been recording a demo for that one.
