What are the characteristics of the anomaly in STALKER 2: Heart of Chernobyl
In addition to the enemies that you can easily defeat with a gun, there are other mechanics in the game that you can only avoid, and they are called anomalies. You'll encounter these anomalies frequently during your adventures. They may be isolated or appear in groups, and you will have a clear signal whenever they are nearby.
As you approach the anomaly, you will hear a beeping sound that will become more intense as you get closer. Once you hear this sound, stop and look around. If you enter these abnormal areas, they can easily cause you to lose more than half of your health in a matter of seconds.
Some anomalies cause instantaneous damage, such as gravitational fields, while others cause sustained damage, such as fire pits.
If you spot a large anomalous group, you may find an artifact nearby. Whenever you see any of these anomalies, it’s recommended to get out your scanner and see if it can detect anything. The default scanner will emit a blue glow when an artifact is nearby, and the glow will become more and more obvious as you get closer.
