Jak II Cheats

Defeat Baron at Palace
First, the Baron will fire his guns at you. Run around to avoid them and take out the Blaster. Fire rapidly at the Baron while avoiding his guns to take off 33.33% of his health.

Second, he will do the same thing, only he will be firing missiles instead. Just stay off of the crosshairs, while firing at him to take off another 33.33% of his health.

Last, he will fire exploding tornadoes. They aren't hard to avoid. The Baron will be easier to fire at here. He also will have an attack that involves ramming you. After the rest of his health is gone, his robot will violently explode.
