The first section is comprised of three labs, each containing a part of the stealth suit Mk II. The second section has two levels. The top level is an observation point for researchers with a virtual reality stealth testing area, and the lower level is a test track for the stealth suit Mk II.
- Stealth suit Mk II disassembled into the three pieces (boots, chest plate and gloves) and is automatically added to the inventory after all three parts are collected. (It has a weight of 25 once assembled.)
- Upon entering the facility, go through first door, and go left down the hallway. The rooms before the end of the hallway are labs #1, 2, and 3. One part of the armor is found in each of the lab rooms (on identical tables showing an armored man diagram).
- Upgrade information for the K9000 mod - Mentat chow stored in office 2's observation area terminal.
- Upgrade information for the K9000 mod - Resla roil stored in the observation area terminal.
- Auto-Doc Upgrade: Implant Y-7 holotape for the Implant Y-7 stored in the terminal just left upon entering office observation area #1 (not to be confused with office observation area #2). Office observation area #1 can be found by entering the reception observation area, and going straight to the other side of the room, where there is a door with a sign on the floor reading "office observation area #1."
- VR simulation note - a paper note in the broken VR simulation room next to a skeleton.
- Sonic emitter notice - found on all terminals in the facility.
- Recipes - Lockpick skill book can be found in one of the vents in the stealth testing lab - the one over the double doors in the reception area. It is possible to reach the vent while standing on the railing in the reception observation area.
- Recipes - Sneak skill book From the test entrance turn right and go through the left door (the one sharing a wall with the "Hold up, Rocketeers!" poster), go through the door just on the right (the one sharing a wall with the REPCONN poster), go through the hole in the wall on the right, go straight through the next hole in the wall, and the skill book is between the two fridges.
- Two Chinese Army: Special Ops Training Manuals: One is in the reward safe upon completion of all the stealth suit tests, and the other is located on the floor, opposite the door in the room where the chest plate for the sneak suit is acquired.
- X-8 kennel key in a suitcase in a room with a force field covering the door to the right upon entry.
- There are three thick red pastes and two thin red pastes in the room where the the prototype boots are located, on a table at the room's south end. This is the only place in the game that thin red paste can be found without the Them's Good Eatin' perk.
- Protonic inversal axe found in the hard-locked stealth test area #2 (VR simulation room).
- Two bottles of Nuka-Cola Victory: One is located underneath a chemistry set, on the first floor, before the testing lab, along with a Nuka-Cola Quartz. The other Nuka-Cola Victory is found near a hot plate in office 2's observation area.
- Three battle brews in a strange cask in the night stalker area of the basement.
- The rare doggie treat can be found in a dog bowl where the night stalkers spawn on the lower level of the main floor.
- Two Stealth Boys. One in the Battle brew room, sitting atop a forcefield that can be disabled with the sonic emitter, and the other to the right of a terminal with a bottle of wine, above the REPCONN managers office.
- There is a LAER on the roof of the facility which is accessed by walking along the pipe joining the north wall of the building to the small cliff. Start from the Big MT west tunnel's left side, near two duffle bags, and go up.
- Preserved meat can be found by following the tunnels in the lower area under the force field on the main floor. The still can also be found in the room.
- Several parts of the Chinese stealth armor can be seen around the facility.
- Towards the end of the test track, there is a sewage pipe that will lead to a clashed room containing a Strange Still. The note on the still reads, "1 vodka, 1 mutant cave fungus, 1 Salient Green," which is the recipe for the still to make battle brew. The room also contains some battle brew in the knocked over refrigerator and a "strange keg" in the corner.
- In the same area as the strange still, if the player character lingers too long, around six invisible night stalkers can spawn in the tunnel and rooms above.
- Each time the test is started, the doors are re-locked. However, there is no additional experience granted for unlocking them more than once.
- The interior wall vents in the observation areas overlooking the test course are actually containers concealing loot. This includes the vents that cannot be reached from the walkways.
- In office #2's observation area on the wall opposite the entrance is a poster for "Love Sets Sail!," starring Vera Keyes.
- In the VR room where the protonic inversal axe is found, it is held by a skeleton, with a note explaining why he smashed the console in front of him. It seems the VR room malfunctioned, and killed its subjects.
- In the rooms where the preserved meat is found, the dolls from Point Lookout can be seen.
- Among and behind the structures to the northeast of the entrance, there are several broc flower and xander root plants.
- The area is a common spot for robo-scorpion spawns.
