Mart Mayhem

Mart Mayhem is a chat game in which you play a convenience-store clerk dealing with unreasonable Karens. Each Karen responds in real time to your words through conversational AI: an effective approach makes them leave, while an ineffective one causes them to escalate.

Shape each encounter

There are five distinct Karens, each with multiple endings shaped by how you respond. Your words guide every encounter, and the game supports open-ended approaches that can make runs play out differently. A playthrough takes 20–30 minutes; seeing all endings takes 2–4 hours.

Switch roles

The included additional content, Who’s the Karen Now?, lets you switch roles with a Karen you have faced and play as the Karen.

AI models and Drinks

The game includes 200 Drinks. Drinks are used when you choose high-performance AI models, which provide more accurate and natural character reactions. Each exchange with these models consumes one Drink, and the included supply provides about three hours of play. Once it runs out, the game switches to the standard AI model; you can also purchase more Drinks.
