[8.3]. Mission 3 - G5 Building: Reconnaissance

Start by eliminating a couple of invisible guards. One carries a necessary key card. Wait for them to attack to reveal their outlines, then shoot them. Exit through the unlocked door.

Proceed down the hall, kill the guard, and activate the control panel to the right of the next door. Enter the door at the end of the hallway.

In this new area, turn right and enter the door within the glass windows. This will trigger lights and more invisible guards. Eliminate them and collect the key card from one of them. Then, enter the door inside the glass case.

Immediately shoot the guard upon entering. Go past the stairs, grab the shield located next to them, and ascend the stairs. At the top, go through the door, turn right, and proceed down a short hallway. Kill the two guards here.

Locate the Alarm panel and ensure the third guard doesn't reach it by killing him as he enters. Then, find and deactivate four control panels in the vicinity to disable the lasers; they will turn green upon activation.

Head through the door next to the alarm and kill the guard at the bottom of the stairs. Continue right down the corridor and into the next room. Defeat the three guards present.

Approach the large control panel and use the 'B' button to disable the damping field generator (optional, but helpful). Return to the room with the Alarm.

From the Alarm room, turn right and face the door. Shoot the guard on the other side through the glass. Go up the stairs at the far end of this room. At the top, turn right, crouch to pass under the low ceiling, and follow the piping back to the area where you previously killed a guard.

Now, deploy the Camspy and guide it along the pipes into the next room. Ensure it is not detected by any guards to avoid mission failure. Successfully navigating the Camspy into the room completes the first objective.

Proceed forward and drop down. Eliminate any guards in the area. If the alarm is triggered, deactivate it.

Go through the door to the left of the alarm, dispatch any guards near the stairs, and ascend them. At the top, turn right, deal with any guards present, and enter the door in the green-marked area on the right.

Inside, turn right and use the Door Decoder on the control panel next to the door. You will need to wait for 1 minute for the vault to open. Defend yourself against any guards that approach during this time.

Once the minute has passed, open the large blue vault at the back of the room and retrieve the Backup Disc. Objective 2 is now complete.

Exit the vault room and proceed straight towards the explosion. Go through the resulting hole in the wall to complete your third objective and exit Mission 3.
