Destroy Dr. Nefarious' Armada is a mission in A Crack in Time, taking place on the Nefarious Space Station. With the hologuise of Dr. Nefarious on their person, Ratchet and Clank infiltrated mission control to use the station's defense laser to destroy Nefarious' armada, preventing him from reaching the Great Clock.
Completing the mission will unlock the bronze trophy Party Crasher.
Walkthrough[]
Unlike the hologuise in previous games, you will not be able to disable this one. You can use the face buttons to issue commands to minions, commanding them to move or be destroyed, or to make them dance. 
can be used to summon Lawrence at one of the hologram projectors. Do so and order him to send the elevator down, then use that to enter mission control alongside Captain Qwark.
Although Qwark implies you can be uncovered, it is not truly possible to fail this mission. Order the Protomantises blocking the doorway to move aside, or order them to be destroyed. Talk to Pollyx, the only non-hologram terachnoid at the central controls, and take control of the station's laser once he moves away. You can also order Pollyx to move if he is in your way, and to have him punished (which will cause him to complain but not hinder your progress). Use the Hypernova Defense Laser to destroy all of the asteroids floating around.
Talk to Lawrence again and tell him to make the fleet land, then use the laser to destroy the only ship in targeting range. After the cutscene, the alarm will be triggered, and you will be forced to fight your way out in "Escape the Nefarious Space Station!"
