EmptyEpsilon

About

EmptyEpsilon is a cross-platform, open-source game that started as a clone of Artemis Spaceship Bridge Simulator but has since diverged from it with new features, including a Game Master mode and multiple AI factions. It's written in C++ using the SeriousProton engine and SDL2, with official releases for Windows, Linux, and Android (beta quality); the host and all players must run matching version numbers to connect.

How it differs from the original

EmptyEpsilon has added features not present in Artemis, including a Game Master mode and support for multiple AI factions.

Getting started

Official builds for Windows, Linux (.deb package), and Android (beta, ARM only) are available from the project's website or GitHub releases; the host and all players must run the same version to connect to a game. Settings are stored in a local preferences file, and the game includes a built-in tutorial covering each crew station's interface.

Known limitations

• networking: Multiplayer requires players to be mutually reachable via same LAN, bridged VMs, or port forwarding; cross-NAT play is not supported.

Community

The project describes its contribution process informally as 'a dictatorship' when it comes to direction, while still saying it values player feedback and welcomes contributions of models, sound, and code.
