Jak 2

Hit 1 person 1time, then steal the closet car near you, (any kind of car). Then a old man from the closet building will try too sell a scatter gun it will cost 5 scull gems then he will go back inside.

Buy the Big Head Mode in the secrets shop. Then turn into Giant Dark Jak. I like this head for Giant Dark Jak better.

This hint is used to defeat enemys faster. First you need to be in Dark Jak form. Then, just keep pressing the square button. In no time, all your enemies will be gone. This is very useful if you're in a hurry.

Go to the South city water area and into the left corner (there should be a small square building with a door). Jump on the roof, orient your camera facing back towards the center of the water area, then roll off just above the door. If you do it right, you will hit the ground, the door will open briefly, and you should be able to get inside. Once inside, you can use R3 to look around, or press up on the camera repeatedly and you will suddenly be in an elevator. At the bottom of the elevator is a cool platform with blue stretching in all directions. You can kinda see the block puzzle in the upper left corner. When you die there you will reappear next to the Titan suit in the underport. This glitch cannot be accessed until you get to "Rescue Sig in the Underport".

After the cutscene before the final battle, hold R1 and you'll transform (or stay as) Dark Jak, regardless of Dark Eco meter.

This mission directly follows riding up the elevator. You'll get a bird's eye view of the city from here.

Carefully cross the bridge. Look to the left when you get to the electrified section. The next electrified section has a path on the right. Next is rotating cubes with spikes on three of the four sides. Be careful crossing, but you need to be quick as well. Look to the right just after the next cannon for the path. Also be careful for falling platforms. Climb back on top of the pipe. Cross another spike cube and look right for the path past the electrified floor. Work your way forward to the rotating cannons and jump to the platform above them. Use the platforms on the right to climb up. Watch the video. Try to leave and get into a boss fight with the Baron. Chase him through 3 stages. Stage one is weapon fire, stage two is missiles, and stage 3 has fire whirlwinds and Baron charges at you.

After Baron is defeated, follow the passageway to the elevator out of this area.

When you are around to many Krimzon Gaurds with guns, get in the nearest vehicle. They will still shoot at you but the vehicle will protect you from the gun fire like shield . This is useful when you have low health.

When you have to deliver the package to the bar, the guards chase you and try to shoot you. To dodge them the best way is to go up and down while you're on a hover-car. If you sway left and right it takes off time, and makes it less likely for you to get to the bar in time. (note) you have to meet the deadline to make the mission successful.

It is possible to destroy Errol in the final race. All you have to do is force him to hit a wall (the large rock one works best). He will not regenerate and the cutscene once you win the race remains the same. This does not work with other races and it is also possible for you to be destroyed as well.
