Vandenberg

Climb atop the elevator. A ladder can be found to access some grates that lead there. The elevator is best found by taking the stairs down from the starting point and moving forward until the guards ask you to die.

Reach the security terminal in the hazard lab. You be landing atop the table in front of it when the points are awarded.

Enter the grate covered area by the interior backup power generator. Its just left of the keypad.

Open the grate behind the reception area (west end) and crawl in. Also accessible from outside towards the rear of the base but its a locked door.

Get to the pit area outside in which lays a dead scientist. Best accessed by entering the area mentioned above then crawling through the small grate next to the metal steps. Its dark, use your light to find.

Find the two crates in the red water area outside the base. On your right as you exit the main entrance.

North of the outside backup generator is a small tower structure patrolled by snipers. Climb to the top then use the large pipe to cross east onto a part of the main building. Two crates containing LAWs are to be found. (Thanks Vaporman.)

Enter the comm 01 bunker where some of the scientist are hiding.

Climb atop the comm 01 bunker, where the dead sniper is located. Best reached by the roof hatch from inside the bunker.

Enter the bot storage bay by the main entrance to the base

For each backup generator activated you'll earn this. 200 points in total.

Enter the Haz Lab storage area. Its the locked door near the Haz Lab.

In the tunnels beneath the base, cross the radioactive part of the tunnel by using the pipes above it. Use the maintenance hatch in the #1 Hazard room to get up there.

While still in the tunnels beneath the base you'll reach a raisable bridge just before find the dead scientist. Raise it to the second level, drop atop it, then head for the crate containing the lockpick. (Thanks Vaporman.)

Exit the tunnel system, in one piece of course.

Establish the uplink to milnet for Dr. Savage. (Thanks Vaporman.)

Approach the front gate to Vandenberg. You can do this at any time during the mission, it doesn't have to be when you leave.

Enter the gas station. Head to the southeast corner. Use some nearby boxes to enter the vent system. Just before you crawl atop some ceiling tiles you'll earn this. (Thanks Vaporman.)
