What is behind the percuros door:
If you look at the "boarder" around the map on the back of the instruction booklet you will notice it looks a bit like writing. Well it is and this is the translation:
"In ancient, dreamless, uninvaded sleep, the silent giants wait to be awakened. Deep will their slumber be, silent their once ecoing voices, untill the world has no memory of their beginnings. In the gloom they will watch and they will wait. those who go to them for answers will return only with new questions. But there will come a time when silence ends. The one who carries the light will awaken the voices. With him, one whose fate was twisted towards darkness in the time before time. When the light bursts from the earth the answers to the questions will begin. But only begin, for still the world will not be ready to learn the truth of it's past, or the secrets of it's future."
This explains what is inside the precusor door at the ending and it fites with what Samos says at the beging.

Faster credits:
Once the names of the Naughty Dog staff have been shown and have disappeared off the screen, hold X or Circle, The credits will speed up and be completed in a few seconds.

Walking on Sad Guys back:
Go on stairs behind him and walk forward.

Stand on Yakkows:
After you round up all the Yakkows in their pen for the farmer, get next to or on top of one. Press Circle and the Yakkow will moo. Quickly jump on top of it. Instead of hopping off like usual, you will stand on its back for a little while.

Stand on Points:
On Geyser Rock, go straight until you reach the Points, but do not go over them. Stand slightly away and slowly walk to the Points. If done correctly, you should be able to stand on one of the Points. Do not move around a lot or else you will lose a health point.

Defeating Spiders:
The easiest way the kill the spiders in spder cave is to use the uppercut move L1 SQUARE. This results in a one hit kill.

Swim Faster:
Instead of holding the analogue in the direction you want to go, keep tapping it in that direction and you will go a lot faster

Dark Crystal locations
1. Hanging in Gnawing Lerker area. Same height as the power cell. It is easy to shoot and find.
2.On the way to the Robot area. It is harder to shoot, easy to hit, and easy to find.
3. Near Dark Cave entrance. It is easy to shoot and find. Use platforms to hit it.
4. Near Dark Cave entrance. Cross Dark Eco with platforms. You should be able to find some clean water on the other side of some Dark Eco. You must use the rolling jump L1 or R1 and jump when you finish rolling or you cannot get across the Dark Eco. Swim down and get close enough and it will explode. It is difficult to get to.
5. In Dark Cave, after you pass the second hanging spider and before the first rotating platform. Near the crystal that is after the second spider, you can find some clean water. Swim down and get close enough and it will explode.

Handstand
To make Jak do a handstand, find a cannon that fires the exploding bags. For example, at the tower at Sentinel Beach. Get on top of the barrel of the cannon. Try until Jak stands still without sliding. Hold R1 and press X. Jak will jump high. Then, press Square to slam down. If done correctly, Jak should do a handstand momentarily.

Map translation:
The following message is the code translated from around the outside of the map that is included with the game.

"In ancient, dreamless, uninvaded sleep, the silent giants wait to be awakened. Deep will their slumber be, silent their once echoing voices, until the world has no memory of their beginnings. In the gloom they will watch, and they will wait. Those who go to them for answers will return only with new questions. But these will come when silence ends. The one who carries the light will awaken the voices. With him one whose fate was twisted toward darkness long ago, in the time before time when the light bursts from the earth the answers to the questions will begin. But only begin, for still the world will not be ready to learn the truth of its past, or the secrets of its future."
