2) Tools: Bring Nitro Some Tools

Tools for basic work: Head south from the scientist bunker, near the bridge. You'll see a train car there. You need to jump onto the train from the bridge, then make your way to the very end of it. Look for a hole in the roof and drop inside. Follow the electrical anomalies down the train car, but duck out of the way when you're about halfway down. Keep going to the end, and the tools will be on your left, just before the exit. Nitro will give you 1000 RU for these.

Tools for fine work: This set is in a building south of the concrete bath anomaly. Go up the ramp and into a fenced-off area. Keep an eye out, as there might be a bloodsucker hanging around. Once inside the building, climb the stairs. The upper floor is tricky, filled with electrical anomalies. Carefully make your way east, and you'll find the tools in a green cupboard at the very end. There's a doorway to your left that leads down a ladder. Nitro will pay you 1200 RU for this set.

Tools for calibration: You have two options here: the Department Store in Pripyat or the Old Service Centre.

• Department Store: Head into the department store in Pripyat. Navigate through the maze of hallways until you find some stairs leading down. The tools are at the bottom of these stairs. Be warned, the building is surrounded by dogs, and inside, you'll encounter plenty of hamsters. You need to take these tools to Cardan.

Old Service Centre: Alternatively, go to the old service centre. Dodge the anomalies and head upstairs. You'll need to kill a Burer that's guarding the area. The tools, along with some other items, are in a small room off the main large room. You can exit down the stairs and then through a locked door.
