BSS Online Multiplayer Client

This feature is still in active development!
When the server updates, all games in progress will be lost. (I will work on a method of handling this soon!)

Please Help Support Me!
  • The best way to support me is to give me feedback on my Discord server.
    Seriously, this is the best way to help me out! Please complain about every minor detail and ask for features you want! Being able to deliver updates and features you want is a big motivator to me!
  • If you'd like to help me pay for my server costs, you can also donate to me at This link.

Planned Roadmap:

  1. Ability to save games in-progress when I perform server updates and reconnect automatically.
  2. Ability to modify BP/Level/Abilities.
  3. Advanced Game Log. (Current log is limited and doesn't show all actions)
  4. Mobile Phone Layout
  5. Several other elements you'll see marked as coming soon.
