10 Best Anomaly Hunting Games on PC 2025

There’s a particular kind of tension in realising something’s changed, but you can’t quite put your finger on what. That unsettling feeling is exactly what anomaly hunting games are built around. You’re stuck watching the same spaces or walking the same hallways, waiting for something to look off. The tension doesn’t hit all at once; it builds slowly and keeps you locked in. If you enjoy games that test your focus and reward a sharp eye, this genre might be your thing. So, here are the 10 best anomaly hunting games on PC that’ll keep you second-guessing what you just saw.

10. Night Security

Night Security takes the Observation Duty formula and gives it a fresh coat of paint. You’re a late-night guard tasked with scanning security cameras, calling out anomalies before things get out of control. The game mixes classic visual oddities with more sinister, creeping presences that appear when you’re least ready for them. It’s tense, unsettling, and a great pick if you’re after a modern take on the surveillance-style anomaly game.

9. Captured

Captured stands out as one of the best anomaly-hunting games, different from other Backrooms games. Instead of just watching stuff happen, you’re actually walking around your apartment, looking for things that feel off. The monsters? They’re weird, each with their own way of messing with you, so you have to figure them out or you’re done. Unlike other games, this one puts you right in the middle of it, like you’re trapped and they’re coming for you. It really keeps you on edge.

8. The Cabin Factory

Mixing things up, The Cabin Factory sends you into haunted cabins instead of the usual places. At first, it looks simple enough. You will soon figure out whether the cabin is haunted or not. But to do that, you really have to explore every corner and look closely. Some weird things are easy to spot, but others take a bit more digging. What makes this game unique is its gradual storytelling approach. Instead of just pointing out anomalies like most games do, The Cabin Factory shows you what’s going on with the family and what happened to them as you find more pieces of the haunting.

7. Shinkansen 0

Taking a spot as one of the best anomaly hunting games on PC, Shinkansen 0 throws you straight into a tense ride where nothing feels safe. You’re stuck on a train, trying to make it to the conductor’s room to stop it, but strange anomalies keep getting in the way. Unlike most games in the genre, this one doesn’t just play with visuals or small changes. It actually puts hostile entities in your path, which adds a real sense of danger.

6. Project 13

Project 13 has you stuck in a loop, walking the same hallway over and over in a psych ward. Your job is to spot anything weird or out of place for thirteen rounds straight. It sounds easy, but some of the strange things are really subtle. Miss one, and you start back at the beginning, which makes it pretty intense. What’s cool about this game is how it messes with your head. The hallway looks almost the same each time, but there’s always something off, making you double-check what you saw.

5. Alternate Watch

Alternate Watch doesn’t just have you watching empty hallways; it keeps you listening, too. Set in a quiet suburban home, this game challenges you to catch anomalies called displacements, and not all of them are easy to spot. Some mess with the visuals, others sneak in through sound, so you’ll need sharp eyes and ears. It’s a clever spin on the classic surveillance-style format, with just enough twists to keep you on edge, earning it a spot as one of the best anomaly-hunting games.

4. The Exit 8

The Exit 8 traps you in a subway corridor, keeping you on edge with its quiet, unsettling vibe. The game mixes creepy atmosphere with the sharp eye you need to catch anomalies. There’s not much of a story, but the real fun comes from spotting the tricky differences, some obvious, others sneaky. At every turn, you’ve got only two paths to pick, so you have to quickly decide if something’s off. Your goal is to make it through the station eight times, all while feeling like something’s watching you, ready to catch you slipping.

3. ATTA – Spot the Oddities in the Strange Hotel

Set inside the Desper Hotel, the game challenges you to explore its floors while hunting for anomalies. The twist? The game turns this looping environment into a hotel attraction, where visitors navigate a series of unusual, puzzle-like rooms. In ATTA, you’ll need to carefully count the anomalies on each floor before moving on to the correct level to advance. While this setup reduces some of the usual tension found in anomaly hunting, this puzzle game still manages to deliver a few well-timed scares.

2. The Stairway 7

Climbing stairs might not sound scary until you’re doing it in a place that never makes sense. The Stairway 7 traps you in a looping stairwell with one goal: reach the top. Every floor looks the same, so it’s all about spotting even the smallest anomaly. If something feels off, turning back is your only option. The game leans into a more frightening style, with demonic-looking anomalies and ghostly figures appearing the further you go. The game delivers sharp, detailed visuals that make it easier to spot changes as you loop through the same space.

1. I’m on Observation Duty

When it comes to anomaly hunting, few games have had the kind of impact I’m on Observation Duty has. What started out as a small indie game quickly grew into a solid series with seven entries so far. Each one flips the formula a bit, adding new ideas while keeping that core tension alive. The gameplay is simple: you scroll through security cameras, looking for anything weird. and call it out before things go sideways. If you’re looking for the best one to jump into, Observation Duty 5 is the smoothest and most polished experience yet.
