One-time offers

Certain NPCs have some unique offers, only available once.

## Akim

After Old documents: part 4, Akim will sell a FN F2000 "Executioner" for 250000RU.

## Informant

Informant is a professional information trader, and will sell you a lot of info on recipes, transitions and miscellaneous leads.
Here's the list of all dialogue lines:

* "I want to buy some information" - 4000RU for the information about Strelok's group, then 2000RU for generic info on Strelok's group, and finally 3500RU for generic rumors on Yantar and Brain Scorcher. Waste of money just like in vanilla, nothing you can't see by playing the game.
* "Been meaning to ask you..."
	+ "Do you have any transmutation recipes?" - 100,000RU for the **Porcupine recipe**
	+ "Do you have any other recipes?" - 500,000RU for the **Sunshine recipe**. The recipe is fake and doesn't work, but once you obtain the real Sunshine after finishing Mystery of the islands, Informant will message you about it and offer a new one-time cyclic for this artifact that rewards 2,000,000 RU and an achievement.
	+ "Any other recipes?" - 150,000RU for the **Electric Porcupine recipe**.
	+ "I'd like to get one more recipe, good sir..." - 200,000RU for **Giant's Younger Brother recipe**.
* "Some knowledgeable people said, one could buy useful info from you. Were they right?"
	+ "Do you have any inexpensive recipes for artifact transmutation?" - 50,000RU for **Mica recipe**.
	+ "What other transmutation recipes do you have?" 75000RU for **Dummy recipe**.
	+ "I've been traveling to Radar from Army Warehouses, but I could never get back. Will you give me a clue as to how do I get back? - 150,000RU for a **transition from Radar back to the Army Warehouses**, available after disabling the Brain Scorcher.

Informant is also selling maps:

* **Blowout shelters map** for 50,000RU or 100 PDAs. It's not an inventory item, it will just automatically mark shelters in your PDA when a blowout is about to start, or when trying to use the sleeping bag.
* **Cave map** for 20,000RU, the same you had in your Cave dream. It's an inventory item, and can be used with a double click. You can have another one for free in Stash in a stash, so this purchase is mostly a waste of money. Moreover, after accepting The medication for Kuzka's Mother you'll be able to give this map to him in his one-time cyclic task for a reward (a random stash), but **only** if you obtained it for free and never bought it from him.

Some dialogues are only available at certain points in the story:

* After completing Combat, Informant's dialogue about the portable battery charging device will continue, starting Lost voltmeter.
* During the search for Voronin's documents, you can buy missing documents for 20,000RU apiece. However, doing that even once will block the final achievement of the game (S.T.A.L.K.E.R.).

## Sakharov

Sakharov offers a recipe for Plasma Caterpillar for 50000RU.

## Docent

After discovering 3 SD cards belonging to Virus in Place of murder during the Article No.58 storyline, bring them to Docent. After that, you will be able to hack PDAs of dead NPCs, receiving a small amount of money (hundreds of RU) as you loot some bodies.

## C-Consciousness Klyonov

After you accept Accompaniment, part 2, Klyonov can sell you for 50000RU the access to the teleport to his room, to save you the climbing time. The teleport to the rest of Warlab is behind Klyonov's back. The teleport to his room can be found on the bottom of the elevator shaft, outside of it, in a corner. It's invisible, and the spot is pictured below.

## Yuri Semetsky

After passing through the sewers of the Dead City on your way to Bunker D-6 assault, he can sell you the Ultra Artefact Detector in exchange for a Red Controller Brain, Isomorph Detector, and Positioner. This detector will sense **all artifacts on the current location** on your PDA map.

Two Red Controller Brains not tied to any quest can be obtained in Huckster's loot and Invisible stashes: Army Warehouses.

This offer is only available before Recipe decryption, so make sure to get it before that point.
