When you initially begin in STALKER 2, everything is off to a rough start. Your contact who was going to help you learn new coordinates to recharge your artifact is dead, and now you need to use a scanner. And to use the scanner, you need to find an artifact.
There’s an anomalous field near the Research Station where you can find an artifact. Unfortunately, Hermann was not helpful in describing accurately how you can track one down. Discovering an artifact in anomalies is a huge part of STALKER 2, and this isn’t the best introduction to how it all works. We can help clear things up for you, and assist in providing accurate details of what you need to do, and what to expect in future encounters when you want to find an artifact.
