This is Master of Orion 3, The Master MOD. It contains new ai which builds ships based off their current tech instead of preset ships. All resolutions of the ships have been improved, the weapons have all been changed to a better quality and seems more intense. It's a brand new experience altogether. There is now a new picture pack which can be downloaded, this picture pack replaces many army pictures eg Mobile and spies. If anyone has any problems or questions just pm me or comment.
This is an image showing you some of the new images that are present with the new download. The images go from top to bottom like this, 1.Battleoids 2.Command Center 3.Marines 4.Squads 5.Infantry 6.Mobile 7.Experience. Please note that not all the new images are present in this image.
