You work the night shift as a cashier in a small minimarket attached to a gas station somewhere in the backcountry.

At night there's only the highway, a buzzing neon sign and the occasional pair of headlights cutting though the dark. Your job is simple: mop the floors, take out the trash, restock shelves and serve anyone who decides to pull off the road.

But the longer you sit behind the register, the more you feel: something is wrong with these quiet nights.

One of your regular customer is no longer human.

And whatever took their place doesn't know everything they once told you. 

AI-driven customers and live conversations

Every customers in NIght Shift Customer is a separate character powered by a large language model:

• Real dialogue, not canned lines.

• They react to how you talk to them.

Memory and relationship.

The AI remembers how you spoke to it on previous nights. Some people see you as "decent guy behind the counter", others as "a loud-mouthed kid at the register".

Relationship level affects how honest and detailed the are, how much they're willing to open up, and whether they'll talk about what's really happening out there.

Routine shifts turning into horror

When the store is empty, you work doesn't stop:

• Cleaning and maintenance.

• Stocking shelves.

• W orking the register.

• Cheating - from both sides.

Over time, small oddities stack up: a glance lingering on the CCTV a bit too long, identical stories from different people, a feeling that some customers repeat the same line with slightly off intonation.

Who among them has been replaced?

The core horror of Night Shift Customer isn't loud jump scare - it's doubt and paranoia.

• The monster copies person, but their conversations with you.

• Listen, remember, connect the dots.

• Test the suspicious ones.

• Make decisions under pressure.
