Crazy doctor

After killing the controllers at Yantar, you descend into X-16 to find the unknown person in an orange suit who was trying to break into X-16, according to the Monolithian squad leader report in Hunting at the Rusty Forest.
== Walkthrough ==
After entering the laboratory, you immediately stumble upon Crazy doctor in an orange suit. Talk to him. He tells you that he was an employee of the X-19 lab, and noticed his colleagues slowly going insane from the "vaccine" the head of the lab has been injecting them with. He injected him with his own vaccine and fled the lab, being the only survivor.
Upon telling you his story, the scientist turns hostile. Kill him, descend into the lab, and kill four controllers there. Make your way to the Yantar collector tunnels, and kill the last three controllers there.
Return to Zakhar and tell him what you learned. He will reward you with an experimental suit made by Vasily.
== Notes ==
* The Armored Sunrise suit is one of the only two suits that make your footsteps completely silent, with another one being Hunting Trenchcoat. This is an indispensable quality for stealth and missions requiring stealth, such as Low-key hunting and Cat and mouse.
