Antares is based on Ares, a game developed by Nathan Lamont, and released for the classic Mac OS in 1996. After a re-release by Ambrosia Software and a major expansion which added support for plug-ins, the game fell into obscurity, as it was not ported to Mac OS X. However, in 2008, the source code was released. Antares is a port of that code to modern systems. There are several issues that need to be fixed before the 1.0 release; the issue tracker contains a list of them. After they are fixed, Antares will have feature parity with Ares in all respects except for multiplayer. The timeline for multiplayer is less certain.
