X-13 Research Facility

The X-13 research facility is a location on the westernmost border of the Big MT.

Layout
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, and the lower level is a test track for the stealth suit Mk II.

Notable loot

 * Stealth suit Mk II
 * Protonic inversal axe found in the hard-locked Stealth Test Area #2 (VR Simulation Room).
 * X-8 kennel key in a suitcase in a room with a force field covering the door to your right upon entry.
 * 2 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 you acquire the chest plate for the sneak suit.
 * K9000 Mod - Resla roil Bathroom observation area terminal has this.
 * Information about Auto-doc upgrade: Implant Y-7 is stored in the terminal just left upon entering office observation area #1 (not to be confused with office observation area #2). You can find the office observation area #1 by entering the reception observation area, and going straight to the other side of the room, where you will find a door with a sign on the floor reading "office observation area #1".

 * K9000 Mod - Mentat Chow information stored in office 2 observation area terminal.
 * Recipes - Lockpick skill book can be found in one of the vents in the X-13 Stealth Testing Lab - the one over the double doors in the reception area. It is possible to reach this 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 your 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.
 * Stealth Boy to the right of a terminal with a bottle of wine, above the REPCONN managers office.
 * There is some thin red paste on the upper level of the Stealth Testing Lab.
