Free Access to Bioprototype & Our Apology
Dear players, We sincerely apologize to all fans of Bioprototype. The game was removed due to the publisher’s policy violations on Steam, and the compensation plan did not meet your expectations. Below is the full story and our new solutions. 1.Cause and Responsibility of the Incident 1. The reason of the removal ●Bioprototype was developed by our team and published globally by a publisher company BD Games. ●In early 2024, the publisher broke Steam rules. Since we're not the administrater of the publisher team, we're unable to know the details of the violation. As a result, their Steam account was permanently banned, and all games they published (including ours) were removed forever. ●This violation had nothing to do with our team or Bioprototype, but Steam required all games cooperated with the account to be removed. ●Important Notice: The removal only affects Bioprototype. Its sequel Bioweaver is a new project, NOT a renamed version of Bioprototype. We regret that some players mistakenly believed the still-available Bioweaver to be a rebranded Bioprototype. We hereby confirm the two are separate entries in the same series. 2. Our Mistakes ●We failed to check risks in the publisher partnership and didn’t draft any legal provisions against publisher's violations. ●We handled the crisis poorly: From June 2024 to the present, in order to maintain the basic operating funds of the company, we chose to focus on developing the new project and entrusted an outsourcing service agency to handle over 100,000 players' key requests manually. During this period, we hoped to explain the situation to Steam to restore the game and communicated with the official through various channels multiple times, but were ultimately rejected. These wrong measures lead to the untimely or missing issuance of keys. ○Early on, we forced players into an Epic key solution due to Steam’s key limit (only 2,000 keys allowed). We ignored that many players prefer Steam, and this decision was careless. We...Read full article on Community Announcements (Ciel)
