Master of Orion mods
A mod changes the game itself, so it is tied to a game version and to whatever loads it. Filter by both and you get the list that will actually load, not the list that mentions your version somewhere in a description.

- Slightly Better Orion Guardian (Outdated?)by shadowwolftjcDoes the Guardian of Orion seem like too much of a pushover in the mid-late game? Well, now that it's sacrificed its Zeon Missiles for even more Death Rays, and now that it has Hyper-X Capacitors and High Energy Focus, it won't be so easy to defeat, even in late-game.1.1k downloadsupdated 10 y ago
- Greenpeaceby nameistoadThis little mod only does two things. 1. It changes the Colony Base so that you can build it on any colony once you've researched it. 5x makes this change, and this mod simply reinforces it.
