Get out of laboratory

After switching the brain in X-16 off, you need to somehow get out of the lab to report to Sakharov.
== Walkthrough ==
The holding cell is filled with all kinds of mutants, including the controller; a powerful anomalous grenade like an Electrica grenade would come handy to avoid killing all this one by one. Here you find Ghost's body; pick his PDA up and listen the audio message in it, which starts the Meet Guide quest. 
BUG WARNING: do not exit to the sewers until you listened to the audio message in full, otherwise the Guide might fail to spawn.
Pick up the documents from his body (the same ones Barkeep sent you for), and proceed to the exit, which is blocked with a movable wooden palette, just like the elevator shaft previously.
Jump down the hole into the sewers. As you pass some weird luminescent slime on a wall, you hear a voice. This is a part of a puzzle that leads to Bonus stash: Yantar, if you want you can follow it now.
Exit the sewers and talk to Sakharov to receive your reward.
== Notes ==
* Ghost's suit can be given to Sakharov as well in his "one-time cyclic" task, if you don't need it. In fact you need to do it, because the recipe given in return will be required in the late game.
== Bugs ==
* If you don't listen to Ghost's audio message to the end, Guide might fail to spawn in Cordon, softlocking you (you can't finish Shadow of Chernobyl storyline without him).
