Kuznetsov's deck

Kuznetsov is asking Marked One to find his missing deck that encodes the location of his stash.
== Walkthrough ==
The cards are usually found on bodies of notable enemies in various quests throughout the game. You only need 30 cards to complete this quest, because the cards are easily missed (bodies can become inaccessible, be destroyed in dynamic anomalies etc). However if you don't bring all 36 cards, you won't get the Card Player achievement, which is one of the three major achievements in the game.
Cards you pick up don't actually go into your inventory, to avoid cluttering it up. Instead, they simply increment a counter which is shown in a message each time you pick another card up.
Some quests with cards are available approximately mid-game, which could mean hundreds of hours in case of OP-2. To unlock all of them, you need to complete the following major storylines:
* Leshy
* "Gagarin" prototype
* Black Doctor's exoskeleton

=== Decoding the deck ===
After picking at least 30 cards up, you'll also need to complete "Baileys" and find Kuznetsov's stash in Red Forest, otherwise Kuznetsov won't talk. Find it and obtain the Note with a cipher from it. With the note in your inventory, go to Cordon and talk to Kuznetsov.
Kuznetsov will decipher the deck into the hint for his stash: "CNPP-1 - a building that is nowhere else". He also says that the hyphen is there for a reason, and that the clue for the location of the stash is hidden in the clue itself.
=== Stash at CNPP-1 ===
Head towards CNPP-1 and look for his stash. The stash can be found in the sign "ЧАЭС" ("CNPP") at the entrance to the CNPP-1 level.
As you can see, the "CNPP" is really in the hint that Kuznetsov deciphered with the help of his deck.
Among other things, the Military photo album will be there. Take it and bring back to Kuznetsov. After that, you will be able to give him all 36 cards. You will recieve the Card Player achievement, 36000RU, and a tipoff of a mysterious sword at the Undiscovered Land.
=== Mysterious sword ===
The sword in Undiscovered Land is marked on your map. It's located on top of the large boulder, stuck in the rock. You can climb to it by jumping on the slope shown in the picture below.
Attempting to pull it out starts The legend of the knight.
== Notes ==
* Fallen Angel obtained in Kuznetsov's stash in CNPP-1 is one of the Artifacts for Dragunov.
* The blueprints in the stash allow you to craft the FN F2000 "Paratrooper" by bringing the requisite parts to Vasily. This gun is very flexible and remains relevant all the way up to the end of the game.
