EmptyEpsilon

![EmptyEpsilon logo](https://raw.githubusercontent.com/daid/EmptyEpsilon/master/resources/logo_full.png)

Started as a cross-platform, open-source "clone" of [Artemis Spaceship Bridge Simulator](https://www.artemisspaceshipbridge.com/), **EmptyEpsilon** has already deviated from Artemis with new features and gameplay, including a Game Master mode and multiple AI factions. We strive to get EmptyEpsilon working on several platforms, and Windows, Linux, and Android are fully supported.

The game is written in C++ with the [SeriousProton](https://github.com/daid/SeriousProton) engine and uses [SDL2](http://www.libsdl.org/) for most of the heavy lifting.

## Download and install

Official releases for Windows, Linux (as a .deb package), and Android (beta quality) are available from the [EmptyEpsilon website](https://daid.github.io/EmptyEpsilon/#tabs=5) or [GitHub releases](https://github.com/daid/EmptyEpsilon/releases). Make sure the host and all players run the same version number of EmptyEpsilon; otherwise, players won't be able to connect.

-   Windows releases are distributed as self-contained ZIP archives that don't need installation. You can expand the ZIP archive and launch EmptyEpsilon directly from the expanded folder.
-   The .deb package requires freetype and SDL2 packages to be installed on your Linux distribution.
-   The Android APK is built for the `armeabi-v7a` ABI and should launch on most Android phones and tablets with ARM processors. (For ARM v8, see [the wiki](https://github.com/daid/EmptyEpsilon/wiki/Build%5CAndroid#build-for-64-bit-arm-v8).) The official ARM APK won't install on Intel x86 or x86_64 devices running Android, but is compatible with [Android Emulator system images that support ARM ABIs](https://android-developers.googleblog.com/2020/03/run-arm-apps-on-android-emulator.html). To build a 32- or 64-bit x86 APK, see [the wiki](https://github.com/daid/EmptyEpsilon/wiki/Build%5CAndroid#build-for-x86).

### Configuration files

EmptyEpsilon settings are stored in an `options.ini` file located in either the `.emptyepsilon` directory of your user home or the same directory as the EmptyEpsilon launcher. For details, see [this repository's wiki](https://github.com/daid/EmptyEpsilon/wiki/Preferences-file).

### Build from source

See this repository's wiki for guidance on [building EmptyEpsilon from source](https://github.com/daid/EmptyEpsilon/wiki/Build). Several Build subpages on the wiki provide steps for building on specific operating systems, distributions, or hardware.
