the best thing ive done is get one of those esf bots, and make a server with a limit at like 20 - 30 on esf_battlearena, add all bots except leave one spot open, thats 18 bots for u morons who cant count
u crank ur pl up to like 70 mil normal goku, then let someone come in and make them be vegeta until thy are at same as u normal. tell them to go ssj and ready up a full pwoered final flash on the front corner of one building on the rim, then hold it. while u go to the other building and charge a full powered spirit bomb and launch it right at the other real person.
(this is all after kicking all the bots out)
now when u fire, tell him to fire. teleport ur way to where the spirit bomb and ff with colide, to the side of it. as soon as they hit, start ur timer, me and my buddy cxgohanjinxc laster 4:21 seconds. it was so long, it lasted that long cuz when the spirit bomb was fired, the goku would fire tones of other weaker sbs at the ps(this would be easier if there were more ppl having fun)
it lasted 4 minutes 21 seconds. it was funny as hell
thats my favorite fun thing to do
