About This Record

The dump includes usernames, email addresses, and password hashes. The studio never released an official breach notice; following the game's shutdown in 2020, the incident remains cataloged under unverified third-party attribution safeguards.

Verification and editorial method

LeakData compares the incident name, date, affected-record count, and exposed data types with accessible sources. Unverified fields are not presented as facts, and records are updated when new evidence becomes available.
