Stalker: Call of Pripyat → Quests → Tools (Zaton and Jupiter)
Both techniques provide special upgrades after bringing a full set of tools. For example, Cardan can modify the exoskeleton to the fourth generation, and you can run in it as if it were a regular suit.
- A set of rough-hewn tools is in the attic of the sawmill in Zaton. Be careful, there are a lot of zombies there!
- A set of tools for fine work at Zaton is located in the Substation Workshops.
- A set of tools for rough work in the vicinity of "Jupiter" – south of Yanov, there's a train car (under the bridge) where the Electra anomaly is running. That's where they're kept.
- A set of fine tools in the vicinity of "Jupiter" - one of the buildings in the Jupiter factory, attic. Beware of the large number of "Electra" anomalies!
- Two calibration tool kits can be found in Pripyat. One is in the Department Store basement. The only problem is, there's a ton of jerboas there. The second is on the second floor of the old KBO. There are a lot of Electra anomalies there, and a whole burer. It's best to approach it with a shotgun or a knife.
