Real-time multiplayer game in development

Jump Jupiter

A rebuild of a 2009 browser game in Unity, running on a server architecture I designed. Release is planned for spring 2027.

The original

Jump Jupiter was released in 2009 as a browser game by spotsonfire, received the “Goldener Spatz” award in 2010 and had more than 964,000 registered accounts before it was shut down in 2014.

The rebuild

I am rebuilding the game from scratch in Unity, on a server architecture I designed. The software is mine and I hold all rights to it. I use the name and the original artwork with the explicit permission of the rights holder of the original. Volunteers help with graphics and moderation.

Status

The game will be free to play, with optional purchases. On 1 November 2026, its community on Discord had 1,489 members.
