To do the lvl 256 its very complicated.
First you will need 2, 2!!!! gold member ships
2nd go into a xboxlive game mode and whatever guy u want to have the 256s u hit b when the timer says 2
3rd do it 1 more time
4 get rid of the other character
5 CONGRATS UR LVL 256!!!!
P.S(ive done this)
Chat with our AI personalities
well you can find a 256 and ask him to see if he knows how to do it and then he could help you guys do the 256 glitch
Just kill the painter bosses paintings in the castle crashers
Just keep levelling up until you reach 256
Castle Crashers is not available on the PSP.
