Daxter

Clank Mask

In the first oil rig level, after the part where you dodge the pistons, you will eventually reach a wall that you can climb inside a cylindrical room. Kill all the spiders on it. Climb it and you will reach a room with a giant wheel in it. Opposite to the room is another climbing wall. Jetpack across to it and climb it. You will reach a ledge. Opposite to the ledge is a smaller ledge indented into the walls of the room that looks too small to jump onto. Jetpack over to the indented ledge and you will be able to stand on it. Smash the picture frame on the ledge, and you will unlock the Clank mask.

Jak Mask

Play the the prison level and go to the second cell block that is patrolled by three guards. Sneak behind the guards and follow them moving counter-clockwise. Collect the key that is hidden behind the second pillar. Use it to open the first door you see to the northeast. Smash the picture on the shelf to find the Jak Mask.

Ratchet mask

Go to the level with the trains. Get to the part at the end where you must climb the tower that has fire beams running up it. Get to the top then go to the right of the exit at the top. Fall down and there should be a mask. Break it and go to the "Secrets" option at the pause menu. Look down and you will have Ratchet mask.

Sly Mask

After you complete the level where you have to nuke the giant metal-head fish with the other exterminator, go out of the warp gate. Have the camera face the warp gate. Go to the left of the warp gate and jump behind the crates. Have the camera face the exit and smash the picture of Sly Cooper. The message "You have unlocked the Sly Mask! Check in the Secrets menu under Extras to wear it!" will appear.

Connection bonus

Use a USB link cable to connect to a PlayStation2 with a saved game file from Jak X: Combat Racing. Then, select the "Connect to Jak X: Combat Racing" option in the "Secrets" menu. You will unlock the "Goggles On/Off" option. To unlock the "Jak X: Combat Racing Vehicle On/Off ", your Jak X: Combat Racing saved game must have a 100% completion in normal mode. The Jak X: Combat Racing vehicle option replaces the scooter with a purple one.
