Master of Orion II: Battle at Antares

Master of Orion II: Battle at Antares (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 version of the game was published by Microprose in 1996, while the Apple Macintosh version was published a year later by MacSoft. Master of Orion II won the Origins Award for Best Fantasy or Science Fiction Computer Game of 1996, and most reviews by critics and players were very favorable.

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 download.
