Artemis: Spaceship Bridge Simulator: 2 Open Source Clones Compared
EmptyEpsilon has diverged from the original Artemis with added features such as a Game Master mode and support for multiple AI factions, and ships official builds for Windows, Linux, and Android with online multiplayer, though the host and all players must match exact version numbers to connect. Space Nerds In Space instead describes itself as a closer, still-in-progress recreation inspired by Artemis, supports only Linux, and its multiplayer is LAN-based rather than online; its README also lists built-in voice chat and a Lua scripting API for mission scenarios, alongside EmptyEpsilon's own scenario scripting support.
