You’re trekking through the Red Forest, the geiger counter is screaming like a banshee, and suddenly, you see it. A shimmering, pulsing sphere of warped reality just... hovering there. In the world of S.T.A.L.K.E.R. 2: Heart of Chornobyl, these "weird balls" aren't just glitches or set dressing. They are the anomalies that define the Zone. If you’ve spent any time in the Chornobyl Exclusion Zone, you know that the "weird ball" you’re looking at is likely a gravitational or electrical anomaly, and it wants you dead.
GSC Game World didn't make these things easy to understand.
Actually, the term "weird ball" is what most newcomers call the common gravitational distortions like the Vortex or the Springboard before they learn the hard way what they are. These anomalies are the bread and butter of the STALKER experience. They’re beautiful. They’re terrifying. They’ll liquefy your bones in about three seconds if you take a wrong step. But surviving them—and even exploiting them—is the difference between a rookie and a legend.
What's With the Weird Ball Anomalies in S.T.A.L.K.E.R. 2?
The Zone is a mess of physics-breaking phenomena. When people talk about a weird ball S.T.A.L.K.E.R. 2 encounter, they are usually referring to one of three specific things: the Gravitational Anomalies, the rare moving "Comets," or the Artifacts themselves.
The Gravitational Anomaly is the classic. It looks like a distortion in the air, sort of a shimmering sphere or a "ball" of heat haze. If you walk into one, it triggers. The "Vortex" variant pulls you in, spins you around, and then pops you like a balloon. The "Springboard" just blasts you with kinetic energy, sending you flying. These aren't just static obstacles anymore; in the Unreal Engine 5 update for the sequel, the visual fidelity makes them harder to spot at a distance compared to the old X-Ray engine days.
Then you have the Fireball or "Comet."
This is a literal ball of fire or electricity that patrols a set path. It’s a "weird ball" in the most literal sense. It hums. It glows. It moves with a terrifying, rhythmic predictability. If you’re looting an underground lab and see a glowing orb bouncing off the walls, don't try to catch it. You'll die.
Why the Physics Feels Different This Time
The developers at GSC Game World put a massive emphasis on systemic interaction. In the original trilogy, anomalies were basically invisible landmines. In Heart of Chornobyl, they interact with the environment. You might see a mutant get sucked into a gravitational ball, or watch a blowout change the location of these hazards entirely.

It’s dynamic.
This means the "weird ball" you saw yesterday near the Lesser Zone might not be there today. Or worse, it’s moved five feet to the left, right into the path you usually take to get back to the Skadovsk.
Spotting the Invisible: Screws and Bolts
How do you deal with a weird ball S.T.A.L.K.E.R. 2 hazard when it’s nearly invisible? You throw trash at it.
The bolt is your best friend. Honestly, if you aren't spamming the '6' key (or whatever your binding is) every time you hear a clicking sound, you’re playing the game wrong. Throwing a bolt into a gravitational ball triggers its discharge cycle. This gives you a brief window—usually a couple of seconds—where the anomaly is "recharging." That is your moment to sprint past.
Some players think they can just outrun the pull. You can't. The "Vortex" has a suction radius that scales with the difficulty setting. On Veteran or Stalker difficulty, the pull is aggressive. You’ll feel your character slowing down, the screen blurring, and the sound of grinding rocks filling your headphones. If that happens, you’ve already messed up.
Artifacts: The "Balls" You Actually Want
Not every sphere in the Zone is trying to kill you. Well, they are, but some pay well. Artifacts often manifest within these anomaly fields. They look like glowing, pulsating balls of energy. In S.T.A.L.K.E.R. 2: Heart of Chornobyl, the "Meatball" or "Soul" artifacts are highly sought after for their healing properties, despite the radiation they emit.
To get them, you need a detector.

Without a detector out, the artifact stays invisible. You’ll be standing right on top of a "weird ball" of valuable energy and never know it. You have to dance between the deadly anomalies, watching your detector’s screen, waiting for the artifact to materialize so you can grab it and run like hell.
The Horror of the Poltergeist
We have to talk about the Poltergeist. If you see a floating, glowing "ball" of orange or blue light that seems to be stalking you, that’s not an anomaly. It’s a mutant.
The Poltergeist is a telekinetic entity. It looks like a ball of swirling energy because its physical body is translucent. It will hurl crates, barrels, and even your own dropped weapons at your head. Dealing with a weird ball S.T.A.L.K.E.R. 2 stalker like this requires a change in tactics. Don't look at the objects it's throwing. Look for the "core"—the center of the glow—and dump a magazine of 5.45x39mm into it.
The blue ones are worse. Those are Electro-Poltergeists. They don't throw boxes; they summon lightning bolts directly onto your position.
Surviving the Zone’s Curiosities
Let’s be real for a second. The Zone is supposed to be weird. That’s the draw. When you encounter a weird ball S.T.A.L.K.E.R. 2 anomaly, it’s a reminder that humans don’t belong here. The game is designed to punish arrogance.
I’ve seen players try to "cheese" anomalies by jumping over them. It rarely works. The hitboxes for these things are often spherical, extending higher than the visual distortion suggests. If you’re trying to navigate a field of these "weird balls," slow down. It’s better to take an extra two minutes to circle a field than to lose forty minutes of progress because you didn't want to throw a bolt.
Real Talk on Gear
Your suit matters more than your gun when it comes to anomalies. If you’re wearing a basic leather jacket, a gravitational ball will end your run instantly. If you’re wearing a SEVA suit with high "Impact" and "Rupture" resistance, you might survive a graze.

- Check your suit’s stats for "Anomalous Protection."
- Carry "Scientific" medkits (the yellow ones). They heal faster and stop the bleeding caused by gravitational distortions.
- Keep an eye on your stamina. If you run out of breath while being sucked into a Vortex, you’re dead. You can’t fight the pull without stamina.
Strategic Takeaways for Stalkers
Navigating the anomalies in S.T.A.L.K.E.R. 2: Heart of Chornobyl is an art form. It requires patience, a bit of bravery, and a lot of metal screws.
Watch the environment. If you see leaves swirling in a circle or grass being flattened by an invisible weight, there is a gravitational ball there.
Listen. Anomalies have distinct sounds. A low hum means fire or gravity. A high-pitched crackle means electricity. A pulsating "thrum" usually means a psychic field or a very rare artifact.
Don't trust the path. Just because a road was safe an hour ago doesn't mean it's safe now. The Zone is alive. Blowouts (Emissions) reshuffle the deck.
Actionable Insights for Your Next Raid:
- Always have the bolt bound to an easy key. You should be throwing it instinctively in any high-danger area.
- Invest in a better detector early. The "Echo" is barely better than nothing. Getting a "Bear" detector allows you to see the direction of the "weird ball" artifacts, which saves time and lives.
- Use anomalies as weapons. If you’re being chased by a pack of Blind Dogs or a Fleshpound, lead them through an anomaly field. Mutants are smart, but they can be tricked into a Vortex if you time your dodge right.
- Check the weather. Some anomalies become significantly more volatile and visible during rain or fog. The electrical "weird balls" are much easier to see at night, but they are also more dangerous when the ground is wet.
The Zone doesn't care about your mission. It doesn't care about your gear. It only cares about the rules of physics—the broken, weird physics that created the weird ball S.T.A.L.K.E.R. 2 phenomena in the first place. Respect the anomalies, or become part of the scenery.
