Infiltration: Secrets

The Infiltration mission hides a few bonus chests along the way.

Locked Room near the diamond pedestal

To open the locked room at the end of the dungeon, you will need to activate a console you find previously in the dungeon. This console is located in the bunker to the right of the bridge that blow up when you cross it. Activating the console in front of my character in the picture will open the locked room at the end for 2 extra chests.

Locked room in the Abandonned Facility

You can find a locked room where a few extra containers awaits you at the end of the Abandonned Facility. To open this room, you will first need to go back to the section where you need to swim in the bio-ooze. At the first crossroad in the bio-ooze, take the path leading below. You will reach a small room with a console in the corner. Activate the console and backtrack to the entrance of the Abandonned Facility. You will find that the first hatch of the Abandonned Facility is now open.

Follow the path behind the hatch (watch out for the poison mine along the way) and you will find a room with a huge computer. Turn on this computer and it will open the room at the end of the Abandonned Facility. Head back to the room where you find the console with the Danger signs that trigger some banters between Lana, Koichi and Nuru. Above this room, you will find the room to your left now unlocked.
