MISSIONEUROPA
Break our games. Vote on the fixes. Then build two new ones with crews from across Europe. Every idea has to survive physics.

The games
Two games to break.
Two to build.
Start with two finished Mission ATLAS games and find everything that confuses, bores or breaks. Then your studio designs a new game, and new players decide which version wins.

How a playtest works
Break it properly.
A playtest is not “I liked it”. It is what happened, why it matters and what you would change. Your notes decide what gets fixed, and the fix is credited to your crew.
- 5 minBriefing
This week’s mission and your twin crew’s latest post.
- 20 minPlay one stage
In groups of two or three. Write down every moment you got stuck.
- 10 minReport
One mission report with your numbers, one feedback card with your idea.
- 10 minPost and reply
Paste both into TwinSpace, then answer your twin crew.
Report desk
Turn your notes into a post.
If your game has a Copy mission report button, use that. Otherwise build the report here. Nothing you type leaves this page until you copy it.
Mission timeline
Six phases.
You are here.
October to April, never more than one lesson a week. The site moves the marker by itself.
Key dates
European crews
Not six parallel classrooms.
One distributed team.
Every school is a crew. Every crew has a twin crew in another country for the whole project. For each new game, two or three schools form an international studio, and the studios are reshuffled for Game 2.

Which crew role fits you?
The build lab
Your game.
Four rules.
Every new game follows the same four mission rules, so the physics stays honest. Everything else is up to your studio.
- 01One physics relationship per game.
- 02Players commit their number before the simulation runs.
- 03The game never shows the answer before the player commits.
- 04Four stages: Watch → Predict → Inverse → Crisis.A bronze medal unlocks the next stage.
Everything else is yours
Setting. Story. Characters. Controls. Help. Look and sound.
You do not need to code. Your crew can send content that goes straight into a game: crisis events, hints, briefings, character lines, debrief facts and translations.
Design brief
One page. Four boxes.
Your studio fills in one box per stage, plus the setting, the player’s role, the help available and how success is recognised. Twin crews review it, teachers check the physics, then it is locked.
1 · WATCH
What does the player watch happen?
2 · PREDICT
What number does the player commit before the simulation runs?
3 · INVERSE
What does the player work out in reverse?
4 · CRISIS
What goes wrong, and what must the player decide?

The decision room
One school.
One vote.
New players in every school test version A and version B blind. Each school’s result counts once, whatever the size of the class. The version preferred in most schools goes forward; a tie is decided by the learning data (smaller errors, fewer hints). Then the crews vote on which features of the other version to carry over, so no studio’s work is lost.
Patch notes · Hall of Fame
Your idea,
shipped.
Every change to a game appears here within 7–10 days of your playtest, credited to the crew that proposed it. Confirmed bugs and physics errors earn bounty points for your crew.

Crew code
Five rules.
No exceptions.
- Call signs, not names. Your real name never appears on this site or in the games.
- Critique the game, never the person.
- Evidence beats opinion. Say what happened, then what you would change.
- Share only what your school allows. Photos, voices and faces follow your school’s consent rules.
- Your work, your credit. Student contributions are published under a CC BY licence with your crew’s name.
This site uses no cookies, no analytics and no accounts. The games keep your unlocked stages only in your own browser.
For teachers
Join the
mission.
Up to six schools, students aged 15–18, 12 lessons (core track) or 20 (full track), never more than one a week. No programming and no required live meetings.
How to join
Contact the project coordinator through the European School Education Platform.
Before the kick-off
- Pupil accounts in TwinSpace
- Media consent, in line with your school’s rules
- Your school holidays in the shared calendar
No lessons needed for this.
Every phase, your pace
Every school takes part in every phase. The core track uses fewer lessons per phase; the full track uses all 20. Blind playtests need a group of new players, such as another class, for part of a lesson, and Launch Week needs an audience.
Useful switches
?test=1- Tester mode: version number, stage select and progress reset (once a game supports it).
?v=A·?v=B- The two versions of a new game during blind playtests.
?station=echo- The Quiet One: assigns a station to a crew.
?crews=echo,drift,auriga- The Quiet One: runs with fewer schools.
