Ratchet & Clank: Up Your Arsenal/Tyhrranosis
 Rendezvous on Tyhrranosis
After the cutscene, go back to your ship. On your way, you will be informed that the new Adamantine Armor is available for purchase. If you can afford it, buy the Flux Rifle now as it will be useful for this mission. Go to your ship and traavel to Tyhrranosis. When you arrive, you will jump out of your plane and drop down to the surface along with a few Space Rangers. Try to avoid the missiles coming at you as you fall.
 Take out the power generators
Once you land, there is an Auto-Vendor nearby which now sells the Annihilator. Once you enter the cave, many enemies will will be in your way. Kill of the enemies and destroy the crates as you go. The Space Rangers won't wait for you, and if they take too much damage they will die. Once you reach the first power generator, which is heavily defended, take them out one at a time. There is a shield that will divide you from the enemies until the generator is destroyed. Once the room is cleared and you've destroyed all the crates, exit the building.
 Destroy the plasma cannon turrets
After the cutscene, there will be an Auto-Vendor nearby, and you will be given a buggy. In this area, the large sunflower plants can be destroyed for additional bolts. Get in speed up and jump the bridge. The monkey will automatically target any nearby enemies and shoot. Follow the past the west and the monkey will take out the enemies on the small platform you pass. To get to the first generator for the plasma turret, you will need to get out of the buggy and follow the path on foot. The first platform you climb onto will have a dropship release 3 mechanical enemies to attack you. Defeat them, long jump across the gap, and continue killing enemies along the path. You will eventually reach a generator inside a cave. Destroy it and you will take out the first turret. Return to your buggy.
Now is a good time to clear out all the enemies and collect any extra bolts. Follow the path all the way west, and you will reach a raised platform with an Auto-Vendor. Jump on the descending platform, and there will be two mechanical enemies waiting at the bottom. Jump up to the next platform and take out the enemies waiting for you. As you run further into the cave, 3 more enemies will attack you. Jump up to the next platform and take out the small Tyhrranoids that attack you along with a larger enemy on a small raised platform.
There is a small dropship enemy ahead, jump on a platform and take it out with a ranged weapon. Continue along the path killing enemies. Don't fall off the platforms, as you will die in the green water. Once you reach the end of the cave there will be two flying enemies. Before jumping down to the regular ground below, be ready to fight off many of the larger enemies consisting of 2 floating enemies, a large mechanical enemy, and 3 large enemies with blasters. Once they've been taken care of proceed behind them and recover some health and ammo. Wall jump up to the platform and take out the enemies and the generator, destroying the second generator. Jump down and head back to your buggy.
Follow the path to the south-east corner. You can take the buggy with you this time, so let the monkey with the cannons take care of all the enemies. Cross the bridge and collect all the bolts, health, and ammo from the crates on both sides of building, and then go in and ram the generator. This will destroy the third turret.
Head towards the last large question mark at the north-east corner. You will again have to get out of the buggy, but if you leave it close-by, the monkey will still be able to help you out. Jump onto the platform, clear out the enemies and head further down the path.
You will reach a gap in the path, on the other side of which are two mechanical enemies. There are crates with bolts and ammo below. Take out the mechanical enemies. When you move to the land they were on, be careful of the two enemies on tall pillars shooting down at you. Take them out with a ranged weapon like the N60 Storm; you will have to jump to target the enemy on the taller pillar.
Wall jump up to the large building in the back, and two small tyhrranoids will attack you. A dropship will also drop 3 large enemies and two others will attack from the side, accompanied by two flying enemies. Kill them without crossing the bridge. Once you do cross, there are two large enemies on the other side, and a dropship will come and release two more with a mechanical enemy for backup. Dispatch them, and then once you round the corner, you can jump up to another platform, guarded by two mechanical enemies. Defeat them and jump up to the last platform to face two more large enemies and two mechanical enemies. Destroy the enemies and the last turret directly and it will trigger a cutscene.
 Destroy the Momma Tyhrranoid
You will be placed in front of the Entrace to Tyhrranoid Mother. Press to enter the control room. There is an Auto-Vendor and a continue point here. It is best to stock up on ammo here, as you will next be up against the Tyhrranoid Mother.
She will initially just chase you around the figure-eight platform. Target her and keep shooting. After a short while, she will jump up, grab the roof, and being spraying the whole area with the large cannon on her back. Be careful and either jump over the shots, or hide behind a pillar. Once her health drops below 50%, a bridge will be raised opening up a new area, and the Mother Tyhrranoid will destroy part of the platform. It will then switch to her perspective as she chases you, while you attempt to evade her missiles. Continue running and take out the small tyhrranoids in the way.
She will chase you to another area that looked like the first. She will again follow a similar pattern, however she destroys the pillars as soon as she enters the room, and shoots two sprays of cannon shots instead of one. Once she is very low on health, she will switch to shooting missiles at you. Use whatever weapons you can to take her out, then watch the cutscene. Once it is complete you will have two new missions: Return to the Phoenix and Destroy the Encampment (optional).
 Return to the Phoenix
The dropship will be ahead of you and once you enter you will receive another set of battle missions. The mission Destroy the Encampment (optional) requires you to complete these battle missions. You can also visit the vendor and purchase the Holo Shield Glove. To continue the main story line, return to your ship, and from there return to the Phoenix. Once you arrive there will be a cutscene, and you will receive the next mission: Complete VR Gadget Training.
