after 30 billion trys i worked up a system to convicts fight...first and foremost play and beat storymode on everyone that way you know their strengths/weaknesses.
1. dont let pico get a gun
2. only jump when you have to
3. when the fight first starts use convicts crouch fierce attack to knock out some samurai hp
4. try to kill off the samurai first then pico
7. after the samurai goes down try to stay on the ground because pico is only really strong in the air
8. after pico goes down sit back and enjoy being a woman beater because nene is almost to easy
9. DONT stay close to a corner, if you have to run left and right across screen try to stop about an inch away from a wall THEN jump over them
now some character tips-
pico-jump and use fierce, it knocks down hp quick
piconjo- worse char to get turned into, he's so slow he's almost useless...best to just stand there and block
s. asshole- juggle people in the air, the computer does it so much it will make you feel good when you do it back
alloy- jump and quick attack
p-bot- if theres less than three stand there and feirce, more than three try to get damage in with jumping quick attacks
nene- useless character....just try not to get hit with her
salad fingers- jump and use long range fierce and quick attacks...you cant go wrong with salad fingers
tankman-keep your distance jump and fierce attack, rocket launcher comes in handy
alien- quick knife attacks on anyone not clumped together following you, requires alot of jumping and dodgeing
hope this helped, i've won more than i've lost using this method...kinda cheap but so is that effin samurai
