Walkthrough
  1. 1
    Holograph Radioactive Isotope: Exit the elevator, go left down the hallway, and through the door on your right. Continue left, then right to a door ahead. Enter the large room, go right, and through the door marked 'Caution'. After the second door, eliminate the two guards. Equip your Camspy, move through the next door into the radioactive room, and advance until you have a clear view of the green radioactive isotope. Press the Z trigger to holograph it.
  2. 2
    Start Security Maintenance Cycle: Return to the starting room where you encountered the first guard. Locate the steel door with grates and wait for the floating robot to unlock it. Proceed down the hallway, past the right turnoff, and through the door at the end. Eliminate the guards inside, continue straight past the large screen, turn right, and activate the nearby screen by pressing B. Then, go to the first screen and press B to activate it.
  3. 3
    Shut Down Experiments: Go back to the large room leading to the Radioactive Isotope. Exit all 'Caution' doors until you are back in the main large room. Go right and through the 'Sector 2' door. Eliminate the guard on the other side and proceed through the door on your right. Approach the scientist to shut down one experiment. Leave and go through the last room on the left. Approach the scientist inside the next door and threaten him to shut down another experiment. Proceed through the large metal door and the subsequent door. Find another scientist, threaten him, but he will activate the alarm and run. Follow him to a control panel, knock him out, and press B to activate it yourself.
  4. 4
    Obtain Experimental Technologies: Return to the main room, enter 'Sector 2', go through the next door, take the second right, and enter the room at the end. Eliminate the guard and scientist, then take the experimental weapon. Exit and enter the door to your left. Take the platform down, kill the scientist and guard, and take the experimental weapon they drop. Return to the main room and proceed through the unexplored door. After eliminating the numerous guards, go to the end of the corridor, turn right, and enter the door. Eliminate the guards, then proceed through the 'Sector Three' door. Navigate past the lasers by waiting for the robot to deactivate them. Enter each doorway until you reach a smaller door labeled 'Sector Three'. Head through it. Continue through the next door until you encounter guards with Dragons. Kill them, take the Dragon and ammo, and use the Data Uplink on the nearby computer to unlock all security doors. Proceed through the door and eliminate the guards in the next room. Enter the 'Restricted' door, then the 'Security' doors to your left until you reach the room with the final experimental technology.
