If your stuck on a boss, heres how I defeated them.
Russel:
Start of by shooting him with your slingshot.When he does an action that looks like a
monkey,run up and down really fast.When russel charges at you he should iss and crash into
the wall and get stuck.Shoot him with your slingshot.Repeat this until he chases you.Then
run as fast as you can and when he gets tired shoot him with your sling shot.If he catches
you, tap Triangle.
Derby:
Once you have defeated the boxers, you chase Derby up into the room upstairs.Knock out the
preps that come, then push down the things that block the door.Once both are blocked,
start fighting Derby.
Johnny:
In the mission The Rumble,You Chase Johnny on your bike.The Greasers pull up a chain and
you fall into the junkyard.Johnny rides round on a bike, which makes him hard.Shoot all
the greasers on the scrap and Pete will run to the Magnetic Thing.Once Johnny rides under
it,his bike gets stuck to it and he falls down.He is easy without his bike.
Earnest:
Hide behind the Vase type things and shoot the cylinders behind him when you get a
chance.
Ted:
Throw the Fire Cracker balls at his defenders to knock them out.Dodge them and pick them
up and throw them.Once all are knocked out, run up a just punch him a couple of times.He
should be knocked out.
Know everyone likes you.But after you do the mission Making A Mark no one does.Don't worry
you gain their respect.
Edgar:
Dodge his blows with the pipe and punch him when you can.Once he runs down the little
pathway pick up the pipe and chase him.He should rip another pipe off the wall.Keep
hitting him with your pipe to knock him out.
Gary:
After this, everyone likes you.Follow him over the planks and up the ladders.When on the
ladders he throws wheelbarrows at you.Dodge them.When you get to the top the bells for so
watch out.It goes into a cinematic of you and Gary arguing then you start grappling with
him.You both fall of, but land on a platform.When your fighting him, it's easy.Everytime
he grapples you tap Triangle and you will fall onto another platform.Once you knock him
out,you fall into the Headmasters Office.You become a student again,Gary gets expelled,
Pete becomes Headboy,Mr.Burton the gym teacher gets fired,and Zoe becomes a student
again.After that you go into Chapter 6, Endless Summer.
I hope this info helps you.Now you are free to roam Bullworth at your will.
