Identify it. Inspect it. Recover it. Real sandbox files, real broken structures, real Cracked Bunker tools — no accounts, no leaderboard, just practice.
No accounts and no cross-device sync — progress lives in this browser's local storage only. No real leaderboard — that would need a server aggregating real data across users, which this site deliberately doesn't have, and a fake one would just be invented numbers. No community challenge submissions, no admin review workflow, no dynamic/procedural challenge generation, no multi-stage "Cases" or Weekly Challenge yet, and no literal skill-tree diagram — the track list above is the honest version of that. Opening a recommended tool never auto-loads the challenge file for you; download it and drop it in yourself, the same way you'd use any two Cracked Bunker tools together. And since grading happens entirely in your browser, a determined user could read every answer straight out of the page source — this is a practice tool, not a secured exam.
