When first entering the silo, a long wide room leads to an open transport lift. Several tunnelers appear further on. To progress, a lift must be activated. The lift leads down to the lower level of the silo. Tunnelers wander the path. The lift area appears only once. Subsequent entry to the silo from the outside leads directly to the following room. The lift exits into a small control room with a desk and computer equipment. There is a stairway to the left that leads downwards, and two doors ahead and to the right. The door straight ahead leads into the level 1 corridor, while the righthand door leads to the level 1 launch deck.
Following the catwalk around the level 1 launch deck leads to a room accessible only by hacking the Hard locked terminal next to the blast door. Past the room is another door that leads back to the corridor noted above. Off the corridor is a locked office, unlockable via the Average locked terminal next to it, and a medical room guarded by a sentry bot. Within the medical room are an Auto-Doc and a commissary terminal.
From the control room, going down the staircase leads to the level 2 launch deck catwalk, with an Average locked storeroom and a staircase that leads down to the remains of level 3. The left of the blast crater by the launched missile leads to more tunnelers before the silo exit to Sunstone Tower roof.
- Eyebot upgrade circuit board for the ED-Ecated challenge - Inside the locked room along the catwalk from the level 1 launch deck. To get there, stay on level 1 and go through the medical area. Go through the rear door of the medical area, and turn right. The Very Hard locked terminal is to the side of the metal door. The circuit board is found in a destroyed eyebot.
- Big Book of Science - In the north corner of the wreckage of the level 3 launch deck after the missile launch, just past a Hard locked safe. The book is to the left when facing the safe. The easiest way to find it is to jump down from the catwalk just after entering the silo on level 2.
Sometimes, the Auto-Doc will not cure addictions.
