Shatter the glass on the tube directly ahead to collect Night Vision. Return to the main hall, heading right from the exit.

Perfect Objective:В Obtain experimental technologies The K7 Avenger is the first piece of technology needed for the Perfect Objective. Smoke the guard, then ride the large lift in the room down. There are two people down there: a guard and a scientist. Return to the main hallway, and across to a silver door, snagging the ammo around the room. Make sure you grab the ammo placed in small alcoves around the lab. Bully him with your weapon until he shuts down the first batch of experiments. When the enemy has been liquidated, head into the lab at the end of the long hallway to your right. Let them come to you and pick them off as they charge. Use the angled column on the right as cover. Through another set of double doors, several guards will be awaiting you. Return through the crate hall you recently cleared back to the hub room. Head up the ramping hallway past the second computer to a silver door. Going back to the first will reactivate the mice, beginning the security maintenance cycle. One will stop the maintenance bots' progress through the hall, the next will reprogram them. See the large, flat computer terminals? Access each of these screens. Using the corner as cover, inch out and pop them with the Falcon. There are a couple of guards lurking here around the bend. Shoot it out and drop into the area below. When the area is clear, head down the sloping corridor until you reach a short glass wall. Line up an angled shot as you cling to the far wall. Some of the baddies can be taken down before you round the corner to the next hall. Often, you can kill them without the guards ever detecting you.

Peek around the corner to line up a shot. There are several dataDyne guards stationed in this winding corridor, each behind a crate. Go through the entrance to the left of the large Sector Two door. The Mine is directly behind the isotope in this area. Keep to the left when you enter the lab, following the path around. Hidden Item: On the outer ring of the isotope room is a Proximity Mine. Pilot the CamSpy back to Joanna and pick it up by walking over it. Take a picture of this structure by pressing the Z trigger. Pilot it through the next set of doors until you reach a large, green isotope. Head through another set of doors marked 'Caution.' Here are a couple of dataDyne personnel lurking here. First, proceed through the 'Caution' doors. The next room is a hub to several areas you'll need to access later. Take them down as they exit the glass to the left. Through this door, several guards are hanging out behind a bulletproof partition. Follow it, eliminating him and heading to the silver door. There is a single guard patrolling the hallway to the left. In a small niche to the right, you'll find a weapons locker computer. Wait approximately three minutes for the guards to clear, then run around the corner. Go through and shoot out the glass at the end of this corridor, dropping into the room below. Before the silver door, he'll take a sharp left, opening a secret sliding door. You'll notice a maintenance bot make his way down the hall you just came from. Then exit and cruise to the left, pausing before the silver door. Wait here (a long time) until you hear the guard's footsteps on the metal plate in front of this door. The best way to do this is to duck back into the elevator as the level begins. Hidden Item: To get the Double CMP150, you have to make it all the way downstairs without being noticed by dataDyne personnel. Gain these weapons: Shield CMP150 K7 Avenger Night Vision Dragon
