Rendezvous with Qwark
There is an auto-vendor here, unfortunately with no new weapons. On your minimap, the nearest ? is the location of Qwark. Defeat the Ninja ahead.

There are two Soldier robots and a Ninja ahead of Qwark. Defeat them, collect the crates and approach Qwark to trigger a cutscene.

Find Nefarious
Enter the ship and you will be taken to Nefarious' ship. In the room ahead, there are 9 Soldier Robots. Either take them out from a distance, or send in some Agents of Doom. There are plenty of crates in the first room, as well as on either side of the second room as you enter. The spaceships here can also be destroyed for additional bolts. Climb the ladder at the opposite end of the room. There are two flying Security Robots, three on the ground, and three more guarding the exit. As you pass the door, a Ninja will attack.

On the other side of the next room, there is a Security Robot on the patrolling on the opposite ledge, with four more behind him. As you approach, the platform at the end will activate as an elevator. Clear out the enemies, and exit out the back of the room, where there are 4 more Security Robots at the far side. Proceed up the ramp, and board the elevator for a cutscene.

Once the cutscene is over, you will have 60 seconds to escape back to the ship. There will be two to four enemies in each room so quickly dispatch them, or simply run by if you have the health to spare. There is also one in the room with the ship. After you arrive there will be another cutscene.

At the end, you will receive Quark vid-comic #4.
