About this game

You’re Just Here for the Night Shift

You are the new night-shift attendant at an underground parking garage.

Whenever a vehicle pulls up to the gate, you must verify the driver, their credentials, the vehicle scan results, surveillance footage, and internal records—then decide whether to let them through.

Inspect the driver. Check their credentials. Review the footage. Search the records. Make your decision.

The job seems simple.

Until the information starts contradicting itself.

Don’t Trust Everything You See

The driver in front of you may not appear on the surveillance feed.

The scan may show an empty back seat, even though something seems to be sitting inside.

The credentials may appear perfectly valid, while the internal records say the person has been dead for years.

The same vehicle may leave completely different information across separate records.

No Time Limit

There is no time limit during inspections.

Drivers will wait at the window, giving you as much time as you need to review the available information before making your decision.

Key Features

  • First-person psychological horror

  • Verify drivers, credentials, surveillance footage, and internal records

  • Detect anomalies through conflicting information

  • Allow or deny entry to every vehicle that arrives

  • No countdown—investigate each case at your own pace

  • The story changes based on the decisions you make over time

  • A confined, oppressive night-shift setting beneath an underground parking garage

  • Multiple endings in the full version

Remember

Your only duty is to inspect vehicles.

Do not leave your post.

Do not investigate irrelevant information.

Most importantly—

Do not mention B3.
