Sugar Grove was a DIA facility with advanced research projects, sigint (signal intelligence) and cryptids divisions. It also ran infiltration and counter espionage against local unions and organized strikes, suspecting them of pro-communist activity. Many different projects were researched here, including large capacity holotapes, EMP based weaponry and brainwashing.
Approaching Sugar Grove from the south, the player character will encounter several protectrons in the parking lot, as well as an automated turret to the left. One can use the main entrance or, past the bunker to the right, access the roof of the structure by crossing one of the fallen trees from the cliff overlooking the building. The complex can be entered through a hole in the roof.
If one uses the main entrance, there are more protectrons inside. After going through the main entrance, you find a double stairway, which leads to a hallway. At the end of this hallway is a computer-controlled doorway, but the doorway is unlocked. Through this door is another hallway, and then a large room cluttered with broken computers and other office equipment. At the end of the hallway on the other side of this room is a stairway leading down a level. At the end of this stairway, to the left, is another hallway, leading up to the advanced design terminal on which the program is stored, guarded by a Major Gutsy and a Mr. Handy.
The back door leads to the underground part of the complex where project Somnus was developed. There are several locked cells and a room with three chairs in front of televisions. This room was the centrepiece of project Somnus, serving for human re-programming. A small laboratory is attached to this room through a hole in the wall.
