Detailed walkthrough[]
After meeting the Think Tank and learning about the technologies needed to reach Doctor Mobius, exit the Think Tank. The quest marker points to the location of the X-13 research facility west of the Think Tank and northwest of the X-66 Hexcrete archipelago. Approaching it often leads to encounters with multiple groups of night stalkers and occasionally cyberdogs and at least one lobotomite group.
Inside the facility, from the entrance door, go through the reception area into the corridor ahead; there will be a force field-covered door to the right, only required for advancing X-8 Data Retrieval Test. Turn left and explore the rooms adjoining the corridor. In each of the room, the player character can find and must pick up a piece of prototype tech (boots, gloves, and chest plate); there are also dedicated terminals in each room detailing the development process. Once all three parts are obtained, the stealth suit Mk II will be assembled and appear in the inventory able to be equipped. The quest objective then changes to getting the suit synchronized to its new wearer and upgraded in the facility's testing area. Continue along the corridor and open the door at the end, where one will find a large chamber with a series of force fields shielding the lower level. The left-hand door leads to a staircase going down there, the right-hand door has a Hard-level lock that leads into a VR room containing a protonic inversal axe, and the forward door at the opposite end leads into the testing area. One must be wearing the stealth suit when accessing the nearby terminal in order to unlock it and enter.
If one is still wearing the suit upon entry, the AI will comment on the testing protocol and direct its wearer's attention to the start area and test terminal below them. They can make their way down (via the stairs) through the doors ahead or simply jump down into the room. One can also follow the doors opposite from the exit and staircase to explore the observation level which contains various loot including gear upgrades for the side quest Influencing People.
In the starting area of the test chamber, activate the test terminal and select the only available option, the Basic Infiltration Test. One can also freely explore the entire testing area beyond the double doors before beginning the test, which reveals many (currently inert) laser tripwire emitters. Passing a Science 50 or Repair 50 skill check per emitter allows one to, respectively, hack or disable them (a hacked emitter goes from a red laser beam to blue and no alarms will trigger when crossing the blue beams). There are also a few patrolling robobrains in the main hallway that one can destroy to make the test go easier (though the suit will comment negatively on this).
Once the test is started, the player character must make their way through the testing area, consisting of interconnected rooms linked to a main hallway, while avoiding being spotted by any patrolling robobrains; if detected, the test will reset and they must return to the test terminal to start again. The objective is to find the administrator's office and retrieve the X-13 document from the wall safe. There are several routes through the area on the lower floor to reach the safe. Alternatively, one can start the test, then turn right from the test terminal and go upstairs to the observation level, then make their way to the area above the administrator's office and simply jump down to reach the safe, avoiding the security measures altogether.
Upon completing the Basic infiltration test by picking up the X-13 document, the stealth suit Mk II will receive its first firmware upgrade (Sneak bonus increased by +10, from +15 to +25). It then recommends returning to the test terminal and trying for more upgrades, starting the side quest Project X-13. Beware, however, as completing the Basic Infiltration Test results in multiple robo-scorpions spawning inside and outside the X-13 research facility that will attack on sight.
If completed after X-2: Strange Transmissions! and X-8: High School Horror!, the main quest Old World Blues will trigger.
