Patches Overview
1.31 Official Patch
Master of Orion II: Battle at Antares (aka Master of Orion 2 and MOO2) version 1.1 was released in NA retail on November 22, 1996. Three days later the first patch, version 1.2, was released to the web. Version 1.2 was used for the EU cd-rom release in December. With patch version 1.3 came the release of the German translation of the game. English and German 1.31 patches were released on April 11, 1997. These two patches are available in the download section below. With patch version 1.31 came the release of the French translation of the game. A Spanish+Italian cd-rom was released in May, containing an integrated executable (2-in-1) that had a few undocumented bug fixes but still carried the same version number 1.31. At the end of 1997, the game was reissued under Microprose's PowerPlus brand. This cd-rom contained a 5-in-1 multilingual exe, again as a version 1.31, bringing the additional bug fixes to the other three languages, but this last official version was never released as a patch.

1.31 Russian Fan Patch
A Russian language version of the 1.31 patch was made by Grig de Griz during 2006-2007. This version is an add-on to the official 1.31 version and does not replace any original game files. To play the Russian version of the game, start the file "MOO2_RUS.EXE" in DOSBox after unzipping the pack into your MOO2 folder. Available in the download section below.

1.40 English Fan Patch
The English DOS version sold online is fan patch 1.40b23 from May 2006. Information about this patch can be found in Lord Brazen's 1.40 patch FAQ.
1.50 Fan Patch
Progressive fan patch for the English, German, French, Spanish and Italian DOS versions of Master of Orion 2. Fixes most known crashes, stalls and network synchronization errors, as well as an abundance of interface and game rule bugs. Game help texts have been corrected and expanded upon.
The patch introduces new features like the option to play against a random number of opponents, a 6th ship design slot, custom build queue lists and new keyboard shortcuts. It has integrated mapgen functionality and supports extensive modding via plain text configuration files so you can easily customize your game. Since patch version 1.50.7 there is (limited) Lua scripting support.
Included mods are 1.50 improved, ICE and Melee, as well as several mapmods. The game can also be played in a classic mode. In this mode no game rule changes are made via config.
A two-part manual (pdf and xls) is part of the documentation of the patch, containing detailed descriptions of bug fixes, new game mechanics, modding options, scripting support and notes on various game mechanics.
The also included MOO2 Launcher allows for easy installation, configuration of several DOSBox options and selection of mod and mapmod before launching the game. The Launcher defaults to 1.50 improved after initial installation. Installing the 1.50 patch does not break your current MOO2 installation. The 1.50 executable is installed alongside the old one and no original files are overwritten. You can still use your original shortcuts to start an unaltered version 1.31 or 1.40 game.
