Jak & Daxter Cheats (PlayStation 2)

In the "Mountain Pass" there is a big boulder bloking the
  way to a Power Cell and a few other things. You need to go to
  "Snowy Mountain" and unlock the yellow eco vent there.(it is
  behingd the trees) Now go back and get the yellow eco vent. then blast
  the boulder away.hint: you need to jump a clif to get the Power Cell.

Collect 45 Power Cells and meet Keira by the machine to the left of
  the Boggy Swamp. Then talk to Keira. She will activate the machine.
  Then climb the cliffs until you reach the Lurker monster known as
  Klaww. You meet 'em, now you beat 'em. I'll cover that on Defeat Klaww
  Part 2.

  

  To defeat Klaww, avoid the giant boulders he throws at you. The last
  one has a Blue Eco cluster. Pick it up, race to the edge of the bridge
  it makes, and wait. Just avoid the boulders he throws at you right
  away. When he takes a while to throw the next boulder, use the Yellow  Eco to blast
fire balls at him. After he gets clunked on the head, run
  back down the bridge and back to the saftey of one of the rocks.
  Repeat twice. The bridge gets incomplete as you run down so much.
  There is one more part before you reach the Volcanic Crater. Look at
  Defeat Klaww Part 3. 

  
This is the last part of a code that gets you to
  the Volcanic Crater. After you defeat Klaww, hop on the rocks that
  appear. You see the flying Lurkers and the Communicator will come on.
  While you listen, head toward the Zoomer. Race to the end of the
  Mountain Pass. If you hit one of the barrel thingys, the Zoomer will
  blow up and you will die. And you will have a hard time avoiding
  those( There are around 300). Destroy the Lurker by the detonator and
  claim your Power Cell.

When you see a yellow eco ball (NOT yellow eco vent) get it and stand in
the same place where you found it and when you shoot as long as you are
in the same place it will automatically charge up again.

Collect 100 power cells and finish the game

When you get inside the Lurker Fort On Snowy Mountain, there's a big
wooden structure right in front of you, climb it. Once you get the
PC(power cell) next to the scout fly and orbs on the top, jump down to
the platform that is the highest one.(you just jumped of it to get up to
the power cell). If you look around to your back you will see another PC
on a different wood structure. You have to go all the way around the
fort on platforms to get to it. But, if you do a running horizontal
launch (L1+square while running) from the platform your on, you can skip
all the hassle of going all the way around and get another Power cell!
Good Luck.

          P.S.  (It
may take a few tries)





Free Precursor Orbs!!!



In the Forbidden Forest Kill the big flower boss. When it's dead jump on
it's head to get FREE PRECURSOR ORBS!!!!!

If you go into deep water, you will hear a heart-beat. Then it will go
faster.go to shallow water quickly!!!! If you can't, you're doomed. A
big fish will eat you even if you jump!It won't eat you if you're on the
zoomer.

In Spider Cave, go to the place where they are building the Precursor
Robot. Ride the elevator to the 2nd floor. Go to where the box with the
flames shooting out of it is. Go on the pole with the platform on it. It
will take you to the other side so you don't go around the whole path.

The most difficult crystal to reach in spider cave is most deffinately
the one in the water near the dark eco pool. The only way to get to it
is to make a role jump by pressing L1/R1 + X in your role. You have to
time it perfectly to make it but it's absolutely doable after some
practice. If that's the only power cell you can't get: don't worry.
There is a total of 101 power cells to collect in the game and for the
alternate ending you only need 100.

blue eco vent: forbidden jungle in the tower

yellow eco vent: snowy mountain behind trees by water fall at lurker
fort

green eco vent: sentile beach. you need to uncover5 vents

red eco vent: none

Avoid the spikey creatures it sends forth until their pointybits
disappear then move in for the kill. The boss will then sprout two giant
leaf platforms ,use them two jump and strike it in the head. repeat this
three times.You'll be victorious! {Forbidden Jungle}

When you are jumping off a high cliff and don't want to lose life right
before your going to hit the ground press 0. You will hover and soften
your landing
