Stalker 2 is set in a fictional version of the Chornobyl Exclusion Zone, where strange anomalies defy the laws of physics, but even that doesn't explain why I so often saw enemies spawn right in front of my eyes.
In our three-star review of Stalker 2, Andy says it's "The best but most broken game I've played all year", and I agree. One of the issues I noticed in my review was that enemies appear to spawn out of nowhere and instantly start hunting you down.
I know the Zone is supposed to be a hostile place, but at one point I was trying to escape from a base I'd infiltrated only to see enemies materialize out of thin air a few meters in front of me and immediately start shooting. Once I'd dealt with them, more would spawn behind a nearby building, and once I'd dealt with them, the process would repeat itself. I must have killed 30 enemies in a place that only started with a dozen or so.
Redditor hayboy117 believes they have cracked the case. "After investigating the ALife system in Stalker 2, I found that NPCs and mutants spawn within a fixed radius around the player," they explain. "This spawning mechanic, coupled with the NPCs' vision distance being greater than the spawn distance, often results in instant hostility from NPCs, which compromises immersion."
A-Life 2.0 is the system that manages NPC spawns and is supposed to be an improvement over the version found in the original three Stalker games. The developers have noted via the game's Discord (shared on Reddit), "There are several known issues with A-life 2.0 system that we are aware of and are working on fixes/improvements. We know that this system is very important to the Zone having an immersive atmosphere, and we will do our best to fix the known issues."

Hayboy117 says they found it easy to tweak the Stalker 2 files to adjust things like bullet damage and weapon wear, so they're confident a lot of mods will come about to help people adjust the game to their liking – there are already several Stalker 2 mods out right now – but they're "disheartened" to discover that the way the system is set up "explains myself and many others frustrations with randomly getting blasted from behind."
They also learned that what enemies spawn depend on your rank and location, and they can have different motivations, such as defending their own base or attacking one controlled by another faction. However, they say "is not a simulated system of non-rendered agents acting on their own motives, but instead an RNG dice roll of contested lairs with a possibility of you stumbling upon one of these contested lairs and witnessing the combat to give the impression of a simulated world."
Essentially, rather than a fully simulated world populated with warring factions whose actions have long-lasting consequences, you're basically just seeing a snapshot of a semi-randomized event that won't matter once you walk a certain distance away.
It's important to note that, just like Cyberpunk 2077 or No Man's Sky, games can be dramatically improved with enough time, and the Stalker 2 devs have already said they're working on issues. They also had to flee Russia's invasion of Ukraine and set up their studio in the Czech Republic mid-development, so if there's any studio we should allow some breathing room, it's GSC.
In the meantime, if you want a quick fix, you can play on GeForce Now if your hardware isn't doing the job, or you could look at some of the best Stalker 2 mods to adjust the game to your liking.
