Fourteen months after a fever sealed the city, the Cordon waves you in. Search what people left behind, keep a body that fails part by part, and stay quiet: the sick hunt by sound.
An independent games label
Worlds you have to survive.
TPMT Games is the games label of ThePostModernTruth. We make games with weight: lived-in places, survival you can feel in your hands, and crews you can lose.

A distinction that matters
Made with AI, not by AI.
Building a game with AI is not the same as asking an AI for a game. Halden: The Cordon is more than a million lines of code, directed, tested and played by a person one milestone at a time. A single prompt does not make a game like this.
Made by AI
One prompt.
- One request, one result. Nobody decides what the game is.
- Nobody plays it, so nobody corrects it.
- It stays as small as the first answer was.
It can give you a prototype. It is not how we work.
Made with AI
A director, and a team of agents.
- A person decides what the game is, and what it is not.
- Every feature is asked for, reviewed and corrected by hand.
- Every milestone is played before the next one begins.
- More than eleven thousand automated tests keep it honest as it grows.
How we make games
Small team. Large ambition.
One director, an AI team and a lot of care. We build big, systemic games and we are honest about how.
01
One person directs
A single developer decides what each game is, asks for every feature, plays every build and sends back what is not right. Nothing ships that was not reviewed by a person.
02
Built with AI, in the open
The code is written with Claude, working as a team of agents. We say so everywhere, and the studio page lists exactly what AI made and what people made.
03
Made to last
Over eleven thousand automated tests keep a very large game honest, and our own tools show how every part connects before anything is changed.
The workshop
Tools we built ourselves.
A game this size is a lot of code, so we made UrbanGraph: our own app that reads the whole game and shows how every part connects, what a change would reach and which tests cover it. It is made for one game and is not for download.
- What breaks if… Every change starts with what uses it, what it reaches and what tests it.
- Always current. The index is read again from the code every minute.
The label
From ThePostModernTruth.
TPMT is ThePostModernTruth: an AI persona band whose lyrics are written by people and whose music is made with AI tools. TPMT Games is its games label, and the same hands make both.
