Evaluation

Abnormality is a co-op ghost-hunting horror game currently in Early Access, developed solo by Patrick at Nightmare Studios. The game launched into Early Access on October 28, 2024 and has been receiving consistent, frequent updates ever since. The major update that was previously anticipated (described as the biggest update the game had ever received) shipped on August 8, 2026 as v0.12.0.0. It delivered 10 new ghost types, a full CCTV camera system, a new item progression system, true first-person view with full body and player animations, rebuilt maps, a completely overhauled ghost AI, localization into seven languages, and more than double the previous number of items. This was followed almost immediately by additional feature patches on August 11, 2026 (custom difficulty options, improved voice chat) and August 13, 2026 (a new cursed item, summoning circle), plus further bug fixes and improvements on August 16, 2026. Importantly, within the August 8 major update post, the developer explicitly stated that map rebuilds beyond Willow Creek Cottage "will be getting their rebuilds pushed as updates over the following weeks & months" — confirming that more content updates are still planned and on the way. The developer's May 12, 2026 post also affirmed the game "is still growing" with "a lot more coming." Development activity is extremely high, with multiple posts in the past two weeks alone. The game remains in Early Access and the developer has made clear that ongoing content — including additional map rebuilds — is planned.

About this game

Abnormality is a realistic co-op ghost-hunting horror game where you investigate locations, gather evidence, identify the ghost, and survive the hunt.

Unlike slower ghost-hunting games, Abnormality lets you actually sprint, allowing for real chases where movement, awareness, and quick decisions matter.

When darkness takes over, night vision becomes your last resort.

INVESTIGATION

A classic ghost-hunting experience featuring 30 different ghost types, each with their own behaviours, personality, known traits, and hidden traits.

Ghosts vary in speed, hunt duration, aggression, and more, meaning no two investigations feel exactly the same. Figure out the ghost type, survive the hunt, and make it out alive.

EXORCISM MODE (COMING SOON)

A sequel to Investigation, where you enter after previous investigators have already identified the haunting.

Set in the same locations, but far more terrifying, this intense gamemode is not for the weak. Exorcise the ghost by uncovering its trauma, learning why it will not let go, and pray you do not get a demon.

THIEF MODE & SURVIVAL MODE (TBA)

More gamemodes are planned, including Thief Mode and Survival Mode.

Create a character that feels personal with detailed customization options including appearance, body features, skin tone, clothing, and more.

You can also customize your lobby.

Horror is the heart of Abnormality.

Ghosts are highly active, intense, and unpredictable, with different traits that make each encounter feel terrifying in its own way.

Expect jumpscares, screen shake, being dragged away from your friends, and even possession mechanics planned for the future.

The game is dark, set in creepy environments, and audio has been a major focus to make every moment feel more immersive and disturbing.

Investigate a variety of haunted locations, including houses, a manor, a chapel, a motel, and maps that change the flow of gameplay, such as a location consumed by a blizzard.

Each location also contains hidden story elements that reveal why the ghost exists and what happened before you arrived.
