Picture for Klyonov

Klyonov in Warlab confirms that he has isomorphs that the Last Day stalkers might have been after. He will give it to you if you complete a job for him. You should:
* Take a photo of the brain in X-16 using your Photo-Gun;
* Take a photo of the special mutated controller in Yantar;
* Speak to a zombified Freedomer in Yantar.
He modifies the Photo-Gun to take pictures, and gives you three shots of the special film.
This quest is timed. You have 12-13 hours to complete it, otherwise the isomorph disappears from your inventory, softlocking it.
==Walkthrough==
After speaking to him, pick up the Isomorph (Cactus) on the ground behind you. This miraculous thing will cause zombified stalkers to remain neutral towards you as long as it's in your inventory.
Head to X-16 through the Warlab transition or through Yantar if you like. Doing the latter will allow you to wipe out the zombified stalkers at the entrance to the lab, which will be convenient later on.
=== Photo of the brain in X-16 ===
The front of the lab will have its regular spawns. Go to the top floor control panel to take the picture of the brain. Quicksave before doing it, just in case.
BUG WARNING: be sure to unequip your primary slot weapon before taking the picture, since the Photo-Gun "projectile" will kill the target before registering the photograph otherwise, and you'll softlock the quest.
The auto-targeting will highlight the thing you need to "shoot" to take the photograph, and sure enough there will be a bloodstain on the pillar after taking the shot. If shoot correctly, you should get a message and a photo in your inventory that can be looked at by double-clicking it.
An electro-chimera will spawn at the exit to the lab. Kill it or run past and go into the sewers.
=== Photo of the mutated controller ===
Almost immediately after exiting the lab to the sewers, you'll stumble upon the Mutated Controller. You can tell it apart from a regular controller by the tendril-like protrusions on its back. Take a photo of it in the same way as before, unequipping your primary gun. Check that you got the message and the photo in your inventory.
Exit the tunnels and return to the above-ground complex to find the neutral zombified stalker Chernomor.
He'll ask for two Antizombine, and if you don't have them on you, he'll say he saw some in the [ tunnel underneath the road]. Grab them, and return to Chernomor. This will start Help to Chernomor.
Complete it, and go into Sakharov's bunker. Marked One will message Lighting about his isomorph findings, and she will invite him to the Monolith Control Bunker (leading to Report to Lightning).
Return to the Warlab and give Klyonov the photos you took, and he'll take the Photo-Gun from you for further study, giving you some isomorph cartridges as a reward.
==Notes==
* Technically, picking up the cactus isomorph moves you into a hidden faction which is also neutral with Mercenaries, Last Day, and the Avengers. Things will get back to normal once you finish the quest.
