Master of Orion II: Battle at Antares

Master of Orion II: Battle at Antares (a.k.a. Master of Orion 2 and MOO2) was the first sequel to Master of Orion. Like the original, it was developed by Simtex; Steve Barcia and Ken Burd designed it. The Windows 95 and MS-DOS versions of the game (both on one disc) were published by Microprose in November 1996, while the Apple Macintosh version was published almost a year later by MacSoft.

The game is still played online, and one group of fans has developed a patch, which fixes some bugs and adds more game set-up options, and a few mods which adjust the game balance (the mods require the patch).

It is now hard to find CDs of the game, but the PC version is still sold as a combination download that includes Master of Orion. The DOS version is also sold as download.
