use the blaster gun over and over and finish him of using your peace maker

it might take a while but if you keep jumpin around and take a couple shots every time you
go down youll beet him. i did that and won with full health. real simple RUNNNNN

use the vulcan AND blaster AND peace maker [dont bother with the scatter gun it wont help]

Keep on doing arial spin rapid fire with either blaster or vulcan by pressing x,square,and
R1 after choosing one of the two weapons. It works.

dude you gotta use your blaster then when hes about on half health yous da peacemaker then
run out ammo(keep shooting him tho)and there should be some rocks near you go behind them
and shoot fro mthere with your blaster and you should win!

unlock unlimited ammo and use the peacemacker over and over again

Shoot with the blaster or vulcan until his face glows then MOVE!!!! repeat again and again
till he dies.

use the scatter gun on the small metal heads and use dark jak when you get 2 bars of his
health down and then shoot him with the blaster or peace maker till he dies and run when
he moves and stay moving

use the infinet ammo cheat: and the invinciblity code: press pause then up up up left down
down down left right

Peform rolling jumps wen health is red wip ur yellow gun and shoot it
