Various NPC services

Certain NPCs offer services you can use throughout the game; they are listed on this page.
For battery recharge, refer to Armor. For repairs, refer to Item condition and repairs.
== Sidorovich ==
If any normally neutral or friendly party has turned hostile, Sidorovich can help settle the matters for 60000, 250000 or 350000RU, depending on the severity of the offence.
Warning: doing this 3 times or more nets you the Chameleon achievement, which blocks you from getting the S.T.A.L.K.E.R. achievement. However in practice you'll need to do this 2 times during the normal course of the story, so doing this even once will block the main achievement of the game for you.
== Kuznetsov ==
Kuznetsov can be bribed for a bottle of Vodka to open his checkpoint for passage, for one hour. Doing this 20 times will earn the Honest Taxpayer achievement.
== Docent ==
Docent can place a marker for any important NPC on the map for 5 PDAs.
== Garik ==
Garik guards the entrance to Barkeep's back room where Docent and Lanky live, and won't budge for free. He will let you pass for 2 Antirads, 1 Army first aid kit, or 2 First aid kits. Doing this 20 times will yield an achievement.
== Vasily ==
After completing Tools for Vasily, Vasily is able to craft unique, significantly upgraded versions of weapons and armor, if you have the requirements for them. You'll have to obtain a blueprint (usually for a major quest), the ingredients (often for another quest as well), and pay him money.
He also offers to craft anomalous 40mm grenades in the late game, and is able to upgrade the Grav-suit to its ultimate capacity, after visiting Kurchatov-37.
See Tools for Vasily#Blueprint locations for the complete list.
== Screw ==
After completing Flamethrower repair and obtaining the Flamethrower "Screw's system", Screw will offer to reload it with Flammable mixture ×300. You can pay in two ways:
* Colloidal cylinder, Gas canister, and a bottle of Vodka. You'll have to give him the flamethrower for a few minutes.
* 30000RU and a bottle of Vodka. This option will take a day.
Note: trading with Max for Vodka might be better than paying Screw with money, as you don't have to give your weapon away for a day. You also don't pay any money (as long as you obtain your vodka from Sidorovich) or pay less (if your vodka is from Skimpy). See Game Economy#Expensive ammo for details.
== Lanky ==
=== Ordinary weapon upgrades ===
Lanky can upgrade certain guns for money. This service is unlocked after completing Army tools. There are two types of upgrades available: accuracy (or recoil, or caliber) and weight. Always make the primary upgrade first (accuracy/recoil/caliber), and weight second; you won't be able to do this in reverse order.
Each upgrade will take a day to complete. You'll get a reminder from Lanky when he's done.
It's usually worth to upgrade any gun you use if possible, as they are significantly improved. There are two types of upgrades: accuracy (or recoil) and weight, but certain guns will obtain much more than that as a side effect. In particular, AN-94 "Sniper" will have longer bursts and higher RPM, making it the best sniper rifle in the early game. M60 and PTRD, notoriously overpowered guns, can also be upgraded for weight. 
Here's the full list of the guns eligible for Lanky's upgrades:

=== Camera upgrade ===
Lanky can upgrade your Camera for 50000RU, so it will show a large green message when a target is in focus for the purposes of some quest. This will make photography quests significantly easier, and will make you stop wasting SD cards. The message won't appear if you already have a valid photo of the target.
Lanky stops offering this upgrade once you finished the Wildlife photography.
=== Computerized binoculars ===
If you have BPOs Binoculars, Lanky can upgrade them for 100000RU, so they will be able to detect turrets.
=== Glock 41 "Auto" ===
After obtaining the Glock 41 as a reward for Punisher or Vityok the Raven's chain, a new dialogue option will appear. Lanky can upgrade it to the Glock 41 "Auto" with a Kriss Super V, Glock 18, and 50,000 RU. Lanky needs more than 1 day for doing this modification.
=== McMillan CS5 "Camo" ===
If you have a McMillan CS5 (from either Voronin's documents search quests or Kalinin's chain) and 100000RU, a new dialogue option will appear. Lanky can paint it and upgrade its optics for 100000RU, converting it to the unique McMillan CS5 "Camo". This raises the gun's overall damage and very slightly decreases its weight, but most importantly adds computerized targeting to the scope.
Unlike his other unique upgrades, Lanky will actually perform this multiple times. This allows you to keep a McMillan CS5 "Camo" for yourself even after giving one to Akill for his chain quest. You won't need the base CS5 anywhere else.
