Break into Megacorp Headquarters

Break into Megacorp Headquarters is the penultimate mission in Going Commando, taking place in the Megacorp Headquarters, Yeedil. Ratchet and Clank met up with Angela Cross again in her home on Grelbin, where she discovered that all Protopets were being produced as clones of the original Protopet in Megacorp's Headquarters on Yeedil, and that by defeating the original, they could shut down Protopet production. As she had her old Megacorp ID badge, the three would be able to infiltrate the facility, though they agreed to go separately to sneak past Megacorp's orbital defenses.

Two platinum bolts can be obtained during this mission.

Walkthrough
This is a lengthy mission filled with combat, so ensure that you are prepared. The Shield Charger is strongly recommended for defense, and by now the vast majority of your weapons should be upgraded. The Plasma Storm and Heavy Bouncer, in particular, are invaluable for this mission and the following boss fight, and having the Kilonoids and Megaturret Glove is also particularly helpful. If you have not upgraded these, consider returning to Joba or Grelbin to do so first. Though the Electrosteel armor is not an absolute requirement, consider purchasing it if you are struggling, as it is easily affordable after completing "The Impossible Challenge!" on Joba or obtaining all of Grelbin's moonstones. However, keep in mind that saving bolts will be helpful for challenge mode. Another option is to obtain platinum bolts and use them to purchase weapon mods for all your weapons. Throughout this challenge, every gadget will be used.

Outer area
At the start of the mission, cross a large bridge to reach a dead end. To proceed, you will need the Hypnomatic. Control a Receiver Bot on a nearby platform, and then use it to control a Receiver Bot on the platform ot the left of that. Deactivate the forcefield and destroy the Protopets, then head forward and control a Receiver Bot on the platform to the right, then use it to destroy the hostile Receiver Bots and control another Receiver Bot on a large platform in front of the main compound on the right. Here, use the Receiver Bots to move through the platform, passing on to others when the path is blocked by an impassable gate, and deactivating forcefields with switches. Eventually, you will reach a switch on the far right end guarded by v2.0 Megacorp Troopers; destroy them and activate the switch to conclude this section.

As Ratchet, use the Swingshot to access the platform in front of the compound, then destroy the Protopets and Megacorp Hover Tanks behind it. Then, head to the back, where there are two platforms leading to the main compound. Destroy the two Hover Tanks that appear, and then jump across the platforms to begin combat. Engage the Shield Charger immediately, and fight the huge waves of enemies that appear. While you cannot go through the main entrance, when the enemies stop appearing, a door on the far end on the left opens into another room.

You cannot cross yet, but use the Hypnomatic to control the Receiver Bot. As this Receiver Bot, you will have to fight waves of Troopers and Protopets, but you have five more Receiver Bots you can control. Defeat as many enemies as you can while avoiding damage, then when the time is almost up, switch to another Receiver Bot, until all enemies are defeated, and then stand on the switch in the door that opens on the end to open the main entrance. Head inside and use the teleporter to get in.
