Description official descriptions

Legends speak somewhere in space of the mystical planet Orion. Created by the Ancients, it remains unclaimed due to a powerful Guardian that orbits the planet and keeps out intruders. These same Ancients long ago fought a war against the Antarans and banished them into another dimension. Now... long after the Ancients empire has vanished, new races take to the stars, wishing to establish their own star empires, defeat the Antarans and become... The Master of Orion.

Master of Orion II: Battle At Antares is a turn-based 4x space empire game and is the sequel to Master of Orion, reinterpreting that game from scratch. Unlike the original the game can be played single player or with other human players. The player takes the role of a ruler of one of thirteen races, while also having the extra option of creating a custom one. They must manage planet resources to build ships and facilities, improving production. Exploration of the galaxy is done via scouts and colony ships, which can establish new planets as part of the empire. Research must also be done to discover and utilize new technologies. Alien civilizations which are encountered can be negotiated with, or ships can engage in combat in a turn-based grid system. As new systems are explored, random events are triggered and strange artifacts found in orbit around unexplored planets. Wormholes can also be found which allow transport across dozens of parsecs into new star systems.

The game can be won in different ways: through conquest of all other races, being voted supreme leader of the galaxy or destruction of the Antaran race.

Best turn-based galaxy-conquest game to date

The Good
High praise? Well deserved I would say. Master of Orion II is still on the top spot of my (very short) list of games with any real(!!) replay value.
The user interface is comfortable, graphics and sound add nicely to the overall mood, but what it really sets in front is the gameplay and the nearly infinite amount of tactics you can (must) use to win a game.
Winning with the Psilons is a piece of cake? Switch to an uncreative race and get yourself slaugthered the next few times. Can you adopt? How can the computer (great AI) grow that fast with the same race?
You will always find settings where the game is a real challenge.

The Bad
Towards the end (espacially if you are playing for a good score), the micro-management gets a bit tedious and if you finished it in one session you might feel a bit drowsy.

The Bottom Line
Turn-based space-exploration and empire-building game (fortunately not) out there. You can get it on earth.

One of the best turn-based strategy games out there.

The Good
Almost anything. The game has good graphics, a powerful yet simple and direct interface, a fun AI ranging in several levels and a lot of customization options. I espacially like the techology system, which allows you to research about a third of all of the techologies in the game, making each decision cruical to your strategy and enhancing the inter-player interaction (trading, spying or conquering new technologies is a must).

The Bad
The multiplayer options. Although there are many possible options for playing with other players, the game constantly crashes while playing Hotseat or Modem. The latest patch helps, but not enough, and the game is not stable. Another problem is the race customization; it's too easy to make a "broken" race, which will have amazing specialty in one field (a lot of money, a lot of science, etc. etc.) and will ruin the game, but this can be easily solved by playing one of the pregenerated races.

The Bottom Line
MicroProse is selling this game, along the original classic, for an amazingly low price. Worth buying, espacially now.

If I could make love to one game, this would be it

The Good
Everything. The diplomacy was awesome..the researching was incredible...the micromanagement was not too tedious, and the whole fact that this is a strategy game at it's greatest makes this a must buy for anyone.

The Bad
The fighting and upgrading ships could use some work.

The Bottom Line
I strongly recommend that any fan of strategy games buy this. Ever wanted to be a Napoleon of space? Here is your chance.

Combat system

The whole tactical ship combat system has many similarities with the system used in Renegade Legion: Interceptor. This not is not only restricted to technical aspects. If one examines the ship graphics in Interceptor more closely, there should be a moment of déjà vu.


The folks at SimTex were calling this game Master of Antares when it was in early development. Later the name was changed to Master of Orion 2 so the game would be more easily recognized by consumers as the sequel to the award-winning original.


  • Loknar’s ship was christened as “Avenger”, exactly the same as the ship you need in X-COM to travel to Cydonia. Even the graphics are similar! Take a look at them and compare! Coincidence?
  • Another coincidence with X-COM? Perhaps the similarity between "Elerium" (the alien energy source from X-COM) and the "Elerians" (the matriarchal psychic race of Moo2) is intentional?
  • In another X-COM coincidence... both Master of Orion games as well as the first X-COM game have an alien race named "Silicoid", however the look of the creatures is very different between the two game series.
  • The Antaran Star Fortress (when you travel to their homeworld via Dimensional Portal) is commanded by a Ship Captain. His (her?) name is Xyphys, the Antaran Warrior, and has the following abilities: "Fighter Pilot* Helmsman* Ordnance* Security* Weaponry*" as noted in the moohero.lbx archive.
  • Phasers, food replicators, transporters, federation type government, the human leader being bald, charismatic and democratic and a few of the ship designs may be references to Star Trek:The Next Generation.
