When fighting the Baron for the first time, he will be in a shielded ship attacking
you. At first he will fire in straight lines at you. Dodge these. After three shots, his
shield will break. Shoot him with your Blaster. Repeat until one third of his health is
gone, then get out of the way as he charges to the next area. Follow him and reload with
the ammo in nearby crates. This time he will fire missiles at you, which follow where you
run. Keep running to avoid these. After two missile attacks, fire at him. Repeat until
another one third of his health is gone. Then, follow him to the last area. His shield is
now gone; fire when you can. He will send fiery tornadoes at you. Shoot him until he runs
away.

When fighting the Baron in Mar's Tomb, pull out the Scatter gun and shoot the mech
spiders that he sends at you. When all of them are gone, he will fire bombs at you. Knock
them back at him with a spin attack. Aim carefully to hit him. Four bombs will take one
third of his health away. He will send more spiders at you. Hide behind the pillars to
avoid being shot by the Baron. Knock four more bombs his way. He will get the Precursor
Stone. Again, stay behind the pillars to avoid him. He will take out sections of the
walkway and shoot only two bombs. If you can turn into Dark Jak, do so and use a Dark Bomb
to finish him. Otherwise, knock the bombs into him. However aiming will be much harder
now; act fast and the battle will be yours.

Note: When you defeat Baron Praxis (in the Tomb of Mar) and leave Mar's tomb,
you will start to see yellow Krimson Guards. The only difference is that they take more
hits to kill.

When keep the JetBoard, you can use it to hover on water and Dark Eco. This can be very
useful when you want to go faster on water if you do not have a Zoomer, or if you have to
cross some Dark Eco lakes.

After you have collected 200 Precursor Orbs, you can start a new game in hero mode. In
Hero Mode, you can get unlimited Skullgems from Metal Heads. Kill the Metal Heads, take
their Skullgems, and after you die or exit, re-enter the level and meet the same Metal
Heads again. They will give you another Skullges. You can easily collect all the Skullgems
needed to give to the Oracle for the new Dark Jak skills. Then, kill yourself and repeat.

Instead of holding L1 then pressing X to do a big jump, press X(2), Circle, jump twice,
then spin kick.

When you have the Blaster rifle and have it equipped, jump (X) then when in the air, spin
(Circle) and fire (R1) while spinning in the air. Jak will start shooting rapidly while
spinning. Use this to easily kill a group of enemies when surrounded.

Collect 65 orbs during a game.

When on foot in the city and being chased by guards, get out of sight and press the Left
Analog-stick towards a wall. You will get stealthy until the panic is over.

Collect 165 orbs during a game.

To get more ammo for any of your guns without getting caught, do the following. Make sure
you are in a place where there are Krimzon Guards (for example, Haven City). Steal a
zoomer from anyone. Accelerate (press X) at a Krimzon Guard, and when it is about to hit
him, get off (press Triangle). Keep on doing this about four to five times to get ammo.
Also, to refill your ammo at any time during a game, go to Haven City and go to the Gun
Course. It is in the Port; look for a Zoomer parked outside a door. Go inside to the first
room where there are several Krimzon Guard Crates. Smash them to find an assortment of
ammo. You rarely (if at all) will find Peace Maker ammo. If you do not max out your ammo
in one shot. Go outside, go to the Hip Hog Saloon, return to the Gun Course, and the
Krimzon Guard Crates should have regenerated.
