To defeat Otto (the final Boss), you need four weapons: The Optical Maser Array, Electro
Rocket (with Shock and Lock-on mods), Shield Barrier, and the PDA. Put up a shield and use
the Optical Maser Array to lower his shield. Then, shoot him with the Electro Rocket. Keep
repeating this until he is defeated. Use the PDA if you run out of ammunition.
Note: This is when you and Otto are the same size, not for the Battle Ratchets,
Giant Otto, or the Giant Clank Battle.

Collect the indicated number of Titanium Bolts to unlock the corresponding skin(s) under
the "Specials" option in the pause menu:

Plundering Pirate Captain skin: 6

Ratchetzilla skin: 6

Troical Vacation skin: 4

Play ten online matches without dying to unlock the Dan skin. Note: The matches do
not need to be done in a row.

Get as high of a Bolt multiplier as possible, then enter or reenter the Dream Realm. You
should appear on a small island. Break the boxes and the small shack to get about 5,000 to
10,000 Bolts (50,000 Bolts in Challenge mode). Go to the second island and kill the birds
that fly through the wall, then destroy the two shacks and boxes on the island. From that
you should get about 30,000 to 40,000 Bolts (120,000 in Challenge mode). In Normal mode,
jump in the water and get eaten by a fish and repeat. In Challenge mode, go to the white
portal on the first island (which should be there after completing the Dream Realm). Exit
the Dream Realm through it, then reenter and repeat as many times as desired.

Start a Challenge mode game. Once you get your Polarizer Gadget, go back to Metalis. Next
to your ship is a grid in the wall. Use your Polarizer on it, then go through the level to
get your Titanium Bolt. Then, use your teleport to get back to your ship. Continue until
you get to Dayni Moon, but try not to finish this level. You will need the boxes at the
start. First, try to get your Bolt multiplier up as high as possible without getting hit.
Try going on the Clank platform over from the ship and use the Titan Deadeye Mine weapon
to kill anything that moves. Then, get in the ship and go back to Metalis. Use the
teleport to go where your Bolt was and get the boxes. One hyper strike should do it. Then,
teleport back to your ship and go to Dayni Moon. Get the boxes at the start. If you need
to do the same thing with the Deadeye Mine weapon to get your multiplier up, do it
quickly. Then, go back to your ship and travel to Metalis to repeat the process.
