Massive(ly) multiplayer online role-playing games
Star Vault is a Swedish game developer building large-scale, persistent online worlds. Our technology powers real-time battles with hundreds of players in a single, seamless world.
A Swedish game studio with a long-term vision
Star Vault AB was founded by Henrik Nyström in 2005 and has been publicly listed in Sweden since 2007. We are a small, independent studio that builds and operates its own online worlds and the technology behind them.
Mortal Online was released in 2010 and continues to expand. More than 500,000 players have signed up to try it. Mortal Online 2 is our next-generation sandbox MMORPG, built on the same proven foundation.
