Ratchet & Clank Going Commando: Part 3: Skirmish in the Wupash Nebula
While Ratchet was on the way to the Maktar Nebula, a female Infobot who admired Clank wanted to see him at his home in Megapolis.
Unfortunately, she was chased away when a certain Thief came to Clank's door, instead. He kidnapped him!
----------
Back at Ratchet, however, he was stuck in a different Nebula in Wupash by a sudden skirmish. You use his ship to shoot them all down.
Controlling the ship, it has its own guns, secondary weapons such as homing missiles, and a shield, which is basically a second health meter. Use all that you can't to shoot down your harassers.
There will be ways to upgrade your ship with better capabilities through collecting Raritanium (which was MUCH rarer in the first game), but that will appear later in this game.
After beating all of the enemies in Wupash, you can then go to Maktar.
