This is a walkthrough for part 2 of Quodrona in Ratchet and Clank: Size Matters (Part 1). You have just beaten lots of Ratchet Clones and you should now be in a room with a grind rail to the right of where you entered.

You can start by solving the grind rail, which will open the door and reveal a room with a couple of doors. Can you guess what will be coming out of these doors? Yep, more Ratchet Clones. This time the Ratchet clones will come in waves out of the doors. Some Ratchets will use their wrench, others will use guns. When you have finally destroyed the Ratchet Clones, a door will open and it will reveal loads of crates in a room. Inside those crates are the final Ratchet clones that you have to beat before going into the final boss. Run across the room and don’t touch the Ratchet clones. Don’t let them touch you either. There should be a big red button. Hyper Strike down on it with your wrench and then a door should open.

Don’t go there yet though, stay and face the crates and destroy the Ratchet Clones one by one. Then you can go to the right of the room (left from where you entered). The door you opened should lead to a corridor with lava streaming down either side. Down the middle there should be a Gadgetron vendor. Restock your ammo and then go through the door. A cutscene will play and Otto will reveal his plans to use his Ratchet Army to take all the intelligence from the most intelligent people in the world. He will then be the most powerful being, blah blah blah blah. So Ratchet has to stop him.

For the first part of Ratchet vs. Otto, you will just have to avoid Ratchet Clones that come out of cylinder things. You do not need to destroy the Ratchet Clones; you just need to avoid them until the time runs out (about 3 minutes). The Ratchet Clones are different now. Some are faster with less attack power and the others are slower with more attack power. Trust me, you can tell who’s who. Anyway, this is the easiest part of the Final battle so enjoy it while it lasts.

When the time is up, a cutscene will play and you will proceed into the second part of the battle. You will now have Otto chasing you and shooting lights which will get bigger and fall down on you. Make sure to dodge them and also dodge the caps in the ground he makes. Eventually you will reach a platform that you need to jump to get across. You will then have finished the 2nd part of the battle against Otto.

Another cutscene will play and Clank will turn into Giant Clank. You now need to beat Otto as Giant Clank. He will have missiles. When he is flying, run away from him. When he goes down, shoot him with your missiles while running towards him. When you have reached him you can punch him. Continue this until his health runs out. When it does, you will have completed part 2 of Quodrona (Click here for an explanation on how to beat Otto in the final round of the battle).
