Brno, Czech Republic – August 8, 2025 – Outspace, the first 3D browser-based massively multiplayer online real-time strategy game (MMO RTS), has reached over 5,000 registered players since its public beta launch. Developed solo by Czech developer Marty (Martin Sadílek), the game runs entirely in the browser, requires no plugins or installation, and supports tens of thousands of players in a single persistent universe.
Players command fleets via point-and-click controls reminiscent of Homeworld, exploring a vast galaxy of 117,428 star systems (five currently open for exploration). Distances and object sizes follow realistic astronomical scales – traveling to Alpha Centauri can take nearly a year of real-time gameplay, and some dedicated players have already achieved it.
To power such scale, Sadílek built a custom game engine from scratch, capable of rendering over 200,000 stars and enabling large-scale 3D multiplayer gameplay in real time directly in the browser. The technology allows up to 50,000 players to share a single game universe simultaneously.
Since entering beta, Outspace has received extensive feedback from its growing community, resulting in refined mechanics, improved performance, and a fully playable experience. The game has recently been featured on IGN, in CHIP Magazine, and in Vortex Magazine.
