Inspiration

Checkout Chaos began as a love letter to late-night retail shifts and the beautiful absurdity of customer service. We wanted to capture the frantic, funny, and slightly terrifying energy of working in a supermarket where everything can go wrong at once.

Enter Gilbo, the overly confident owner of the Grand Line Supermarket Chain. He’s convinced the future of grocery shopping lies in the Metaverse, and he needs your help to make it happen.

What it does

Players take on the role of supermarket employees trying to keep Gilbo’s digital empire running. Stock shelves, check out customers, clean up disasters, and work together to survive the constant chaos of unpredictable AI shoppers. It’s teamwork, comedy, and catastrophe all rolled into one messy, glorious shift.

How we built it

We combined playful co-op mechanics with expressive NPC AI behavior. Our design draws from real-life retail quirks and multiplayer sandbox games, blending simulation with slapstick. There are some really fun AI characters like Gilbo, Jade Class, and Alla to talk to that has been a blast to learn how to build and QA.

Challenges we ran into

Editing at the same time between up to four people caused a lot of issues, as well as getting the AI to respond to listen events. However, we were able to figure most of those things out, as well as ways to check-in on who is working on what.

Accomplishments that we're proud of

We made a world that feels alive and unpredictable. Gilbo became an instant team favorite, embodying the charming mix of clueless boss energy and heartfelt enthusiasm, and we really love the world we made around the supermarket.

What we learned

Making a supermarket game is complicated.. do we let people set prices? Inventory? Customer behavior? A lot of new things were learned through trial and error
