Specter: a 14-level adversarial OSINT wargame with no walkthroughs or skip buttons

Specter is a free, 14-level OSINT (Open-Source Intelligence) wargame on BreachLab, with levels 0–8 currently live. It features ephemeral per-session containers and cryptographic flags that prevent sharing from being useful. The challenges range from passive reconnaissance (e.g., WHOIS, DNS, GitHub hunting) to advanced techniques like geolocation via shadows, deepfake analysis, and travel-pattern reconstruction, with adversarial decoys and persona-burn penalties. The game is designed to be solved only through the intended paths, with no signup required and scoring tracked on-platform.
