Soap for Fima

Fima the Charcoal is asking you for 5 pieces of soap. Not just any soap, but the particular one, located at the Construction Site, and gives you 10 Impulse grenades to knock it down from the platform it's located on.
Regarding the stalker he mentioned while being in Captivity, Fima says that he was looking for some safe and a box in Labyrinth before being captured by Monolith. In the box there was a code to the lower door of the Labyrinth main chamber. The stalker was going to escape from Labyrinth to Yantar and then travel to the trader at Agroprom.
== Walkthrough ==
The soap can be found on a platform hanging from a [ tower crane]. You can use Fima's impulse grenades, but it's easier to just shoot the platform and tilt it enough for the soap to drop down. As usual, shotguns have the strongest physical kick due to the number of pellets.
Bring the soap to Fima, receive your reward. He gives you a recipe, but only the first half of it. He doesn't know the second half, but advises to speak to "Agroprom merchants" (Adrenaline being the only one) to find out.
== Notes ==
* Despite Fima saying it's just a "half" of the recipe, it's fully functional. This is a known shortcoming in the NS plot; Arkhara was probably going to add a quest with the second half but never did in the original Narodnaya Solyanka, which is used as a base for OP-2.
* Additional pieces can be potentially found in Fima the Charcoal's stash in Swamps, which is one of the named stashes and can be randomly obtained from any NPC body or Informant's PDA exchange.
* Impulse grenades aren't used anywhere else in the game, so don't bother saving them. You can't push friendly NPCs out of the way with them either - it still counts as an attack, like with flash grenades. You can use them to push physical items, though.
