Season map
One city, five seasons, four shells. The web app plays Seasons 1 and 5; each platform app carries its own season plus the whole game.

How a mission works
The city is the interface. The range is the target. Your real tools do the work.
-
01
Read
Each job opens with the lesson it teaches: the concept, a guided lab, the failure modes.
-
02
Break
The engine starts the target named in the job — a store, a clinic, a phone, a vault — on loopback. Burp, curl, x64dbg, jadx, gdb: whatever the season teaches.
-
03
File
The Wire only pays for proof. Checkpoints, quizzes, notebooks and reports become claims your journal records.
Downloads
Every bundle carries its own engine, all 93 missions and the whole range. Hash-verified on this page; nothing leaves loopback.

Bundles include a private CPython runtime and the rendered soundtrack. Verify with the sha256 shown on each card.
Account & sync
Optional. An account keeps your journal across machines; the game never needs one to run.
Progress sync
Your journal state (signal, standing, filed missions) can be pushed from the game and pulled anywhere.
