Master of Orion II: Battle at Antares is a singleplayer and multiplayer 4X and TBS game in the Master of Orion series.

Updated versions of the game included a Windows-native executable Orion95.exe. This version was highly unoptimized and particularly laggy when playing multiplayer games.

Notes

  1. 1.0 1.1 1.2 1.3 1.4 1.5 File/folder structure within the installation folder reflects the path(s) listed for DOS game data. For the GOG.com release, file changes in DOSBox are redirected to <path-to-game>/cloud_saves/ even if GOG Galaxy is not used (this folder contains all redirected files, so some files in the cloud_saves folder might be temporary files or other files that do not contain saves or settings).
