The premise
What if learning how systems work felt less like a lesson—and more like finding a way in?
About the project

Built around
a sharp idea.

Terminal Zero turns the logic of computers and networks into an approachable game world. Players investigate simulated systems, notice patterns, test ideas, and discover that the shortest path forward is usually a better question.

The goal is not to reward memorization. It is to build intuition: observe carefully, understand the rules, and use that understanding creatively. Each challenge should leave the player feeling a little more capable than when they arrived.

Design principles01—03
01

Curiosity first

Progress begins with observation and experimentation. The game invites players to poke at the edges and learn from what responds.

02

Systems as puzzles

Technical ideas become legible, interconnected challenges rather than walls of terminology.

03

Earned mastery

New possibilities open as the player’s understanding grows—not simply because a number went up.

The journeyDone / Next

What's done

  1. 01Seven complete missions, from an exposed backup to a full memory-safety exploit — each one ends with the fix, not just the break.
  2. 02A safety model with real teeth: every target is fictional, every command is simulated, nothing here ever touches a system you don’t own.
  3. 03Localized in English, Spanish, and French, while the terminal itself always stays authentically technical.
  4. 04The first two missions, live and free to play right now.

What's next

  1. 01The rest of the campaign, unlocked — plus certificates and a real progress profile.
  2. 02A technique catalogue organized around the frameworks the industry actually uses: OWASP, MITRE ATT&CK.
  3. 03A live threat monitor connecting real cyber news to the missions that teach the defense.
  4. 04Classroom and team training for people who want to learn this together.
Our vision

Terminal Zero’s long game isn’t a course you finish. It’s a place curious people come back to — where breaking a fictional system on purpose is how you learn to defend a real one, one mission at a time.
