At the beginning of any level press Up, Left, X, Right, Circle, Square, L1, R2, L1, Down, X. You will immediately be credited with all Ecos and Power Cells.
Faster Credits
After the Naughty Dog staff's names have disappeared off the screen, hold X or Circle. The credits will be shown at a much faster speed.
Faster Zoomer
Hold L1 and R1 to go faster on the Zoomer. This will make it less maneuverable, however.
Fly!
In training mode, get Blue Eco to go through a door; instead jump off the mountain side with rocks. If done correctly you will be flying until the Blue Eco runs out.
NOTE: Save First.

How to defeat the last boss
Before you go down make sure you break all the boxes for full life. Then get the blue eco and go down and fight. What you have to do first is get the yellow eco and shoot at its eye. Now the giant robot will shoot things into the dark eco and lurkers will come out. Keep your distance from them and shoot at them with the yellow eco. (Close up attacks won't work because you will get hurt). Once you defeat all of them, get yellow eco and shoot at the robot again. Now the robot will shoot little red balls out. They will explode rings. Jump over all the rings. Now get yellow eco and shoot at the robot again. Now the robot will start shooting yellow beams at you dodge those and get yellow eco and shoot at the gun it is firing with. Now white eco will appear. Bombs will be shot at the ground but just ignore them. Wait for the white eco to appear on the ground and get it. Now you won the fight.
How to get 100%
To finish the game 100%, you have to get all of the 2000 precursor orbs, get all 101 power cells and put them on the door at the last boss.
Power cells in geyser rock

Secret Ending
Get 100 or more power cells and finish the game to see a secret ending. If you get less than 100 power cells, you wont be able to see it.
Shoot Cannons Farther
The cannons at Misty Island and Sentinel Beach will shoot farther if you hold Square, or Circle and X.
Super Jump
Press L1 + X. If timed correctly, you will go into a crouch position and spring higher that you would by double jumping (X, X).
Swim Faster
Instead of holding the Analog-stick in the direction you want to swim, keep tapping the Analog-stick in that direction. By doing this, you will move about twice as fast.
Unlimited Health
Pause the game and press Up, Left, Left, Down, Right, X, and Triangle. Your health will not go below zero.
Very Powerful Attack
While punching, jump and you will do an uppercut. Then do a spin kick or a dive for a very powerful attack.
