In STALKER 2: Heart of Chornobyl, status effects play a key role in the game’s survival aspects. These effects aren’t just small annoyances; they add to the challenge of staying alive in the dangerous Zone. They affect what your character can do, including how fast they move, how much stamina they have, how well they can fight, and whether they can rest properly. If you ignore these conditions, you could face serious problems, which can lead to death. Some status effects hit you hard and fast, while others build up slowly, gradually making things tougher.
