Level up Don Kreig so he is strong in attack and use his ranged attack (A+RT)Then when thre are like 25 left go kill them

it´s also very easy with buggy... first of all walk into the center and use your super attack chop chop festival... so the canondog is dead... than go for the guys with the pistols and well the rest is easy afterwards and it´s enough time

First, press L-a x(chop chop big chase) so they get hit and killed quicker. jump up and kill pirate a the ones who keep shooting at u nonstop.Then throw a weapon at mr.4, when hes stunned kill him.use accel heat lvl 2 or 3 alot, it will be very effective. then kill all enemies before they respawn so they dont get to hit u
