Master of Orion II: Battle at Antares/Diplomacy is scouting

Many strategy game guides say things like "Scout early and keep scouting all through the game" to see what your opponets are doing.

In MOO II your ships can't discover much your opponents from a distance and, even if they enter a system occupied by an opponent, all they can see is colonies' current and maximum populations, the types of defenses that they have (e.g. Star Base, Missile Base; but not how advanced these are) and the nature, mineral wealth and any special features of planets in the system.

But you can get a lot of more useful information without visiting opponents' systems. It's impossible to produce a comprehensive guide to interpreting this information, because the possible variations are endless. You have to develop your ability to interpret what the relevant screens say - and what they don't say, which is often as important.

So this page presents an example of how much information you can extract from just 2 screens.

Before we get into details, the lesson is: Use the Races (diplomacy) screens to check out all known opponents at least every 4 turns. The example below shows an opportunity. In other cases regular checking may save your empire by warning you of a threat.

Race statistics

This tab of the Information Screen tells you the advantages and disadvantages of the founding race of each empire with which you have contact. It is accessed from the main Galaxy screen (hotkey I).

Look at the entry for the Silicoid empire:

• They're Tolerant and have an industrial bonus.
• They're Lithovores.
• They're not Creative (unlike the Chessplayers and Psilons).

By the way, we're the Chessplayers - check out the race design.

There's another item that's important for the example below - it's game date 3516.8, i.e. turn 168. You will more usually get that information from the top right corner of the Galaxy screen, since every turn starts there.

Report Screen

The Report screen is accessed from the Races Menu and gives information about another empire. The large panel on the right tells you what techs the other empire has. There are so many possible techs that the display is split into 4 tabs, each of which is scrollable. This example shows the "Colony" tab, which tells you about techs that help to make this empire's colonies more productive or provide ground-based and orbital defenses for them.

This example of the Report about the Silicoid empire is also from turn 168 of the same game.

The left panel is fairly simple:

• The Silicoid empire's ruler is an Aggressive Industrialist. The main priority of "Industrialists" is usually building up their industrial capacity; but that's not an infallible guide and, as we'll see, this empire's industrial tech is very basic. "Aggressive" means this empire would instantly attack if it thought it could get away with it; the fact that it hasn't suggests it doesn't think it's strong enough.
• The Silicoids have no Spies in our empire - if they had, their icons would appear in the box that says "No active Spies." So they are not currently trying to steal our techs or sabotage our assets. Don't read too much into that - a clever player stockpiles Spies and inserts a large number in one turn, hoping to catch the opponent unprepared.
• The Silicoids are not currently involved in any wars or alliances.

In this example the interesting information in the "Tech Review" panel on the right:

• They have only the lowest-tech industrial and research buildings.
• They appear to have no income-enhancing techs (if they had, the panel would have another heading, "Money").
• They have only the most basic defensive buildings.
• They have discovered Dimensional Portal, which is at the 3rd-highest level of the Physics tech tree.

Now for some interpretation:

• The fact that the Silicoids are not Creative suggests they don't have the powerful Disruptor Cannon beam weapons, as that is the other tech at the same Physics level as Dimensional Portal; but it proves nothing, as they could have obtained the Disruptor Cannon tech by other means (tech trade, spying, conquest). The 2 previous levels contain some powerful weapons, so we need to check the "Weapons" tab. In the game which supplied these screenshots, the "Weapons" tab told us the Silicoids' best beam weapon at this point was Neutron Blaster (in Physics), but they also have the powerful Proton Torpedoes (in the Power tech tree; and, unlike most torpedoes, they hit instantly, not a turn or 2 later), which means their ships can do considerable damage even if they have poor computers; and their best missiles are the basic Nuclear Missiles.
• The Silicoids have primitive research tech but have researched to very high levels in Physics and Power. With such limited research capacity they have very probably neglected other military techs, so we need to check the "Equipment" tab.
• As we suspected - in this game the Silicoids only had Class 1 Shield and Titanium Armor ("cardboard").

We should compare that with our own military techs; if we're not sure of them all (quite possible, as there are so many) we can check the "Tech Review" panel of the "Information" screen, which has the same layout as the "Tech Review" panel of the Report screen). At this stage in the game our empire has Zortrium Armor, Class 5 Shields (will make Neutron Blasters almost completely ineffective; Inertial Stabilizer (makes our ships harder to hit with "beams", 2 types of ECM Jammer (the best defenses against the Silicoids' Proton Torpedoes; but our ships are not equipped with ECM Jammers because we wanted to use the space for other things), Cybertronic computers (makes "beam" weapons very accurate), Gauss Cannon (the best weapons in the Force Fields tech tree; each of our ships has 4 HV Gauss Cannons and will punch holes in Class 5 Shields in 2 combat turns, and in lower tech shields instantly), Mass Drivers (fully miniaturized as they're from low in the Force Fields tree; AF, i.e. fire 3 times per combat turn; 15 AF Mass Drivers per ship will shred targets that are unshielded or whose shields have been broken down by the Gauss Cannons), and Structural Analyzer (doubles all damage that penetrates the target's shields). We have Ion Drive and are currently researching Anti-Matter Drive.

Our ships are far better than the best the Silicoids can produce; and it's quite common that over half of an empire's fleet is below its best tech level, because moving older models to shipyard colonies and upgrading them takes time. The most difficult battle we'd be likely to face would be 2 of our 3(!) Battleships (2 now, 1 will be completed in 4 turns) against about 10 of the Silicoids'. Even if all the Silicoids' warships are equipped with Proton Torpedoes we have a much better than 50% chance of losing no ships (our ship's superior computers will enable them to shoot first, and we expect to make 3 to 4 kills per Battleship per combat round because the Silicoids' shields and armor are so feeble; ours are quite tough, so we expect our ships to survive the Proton Torpedoes fired by 2 to 4 Silicoid ships) and the Silicoid fleet would very probably be annihilated (an absolute maximum of 3 survivors, and they'd have to be very lucky). All these screens also tell us our ground combat techs are far superior in every way; we'll skip the details.

The "Colony" tab told us what to look for, and what we found says loudly and clearly, "Attack now, before they fit all their ships with Proton Torpedoes or get Mauler Device" (a brutal beam weapon that never misses, even if its owners have no computers at all; it's at the next level of the Physics tech tree, and the Silicoids may be researching it now).

As the Silicoids are Lithovores we won't have the burden of feeding any of them; and they're Tolerant, so we can build up the economies of conquered colonies as fast as we like. They're a very inviting target as well as an urgent one.

So we make our non-shipyard colonies build 15 Troop Transports, timed so that the last is completed in the same turn as our 3rd Battleship. Our one obstacle is that at this stage our Iridium Fuel Cells do not give our fleet enough range to reach the Silicoids' nearest colony. We could switch research from Anti-Matter drive to Uridium Fuel Cells, which would provide just enough range; but it would take us 6 turns to get Uridium Fuel Cells. So we make an Outpost Ship, completed in the same turn as our 3rd Battleship; we're gambling that a system a little over half-way to the the Silicoids' nearest colony contains a planet, Gas Giant or Asteroid Belt where we can create an Outpost, which will put our ships within range of several Silicoid colonies.

The results were:

• 4 turns after this Report our 3rd Battleship was completed and our whole fleet headed for the intermediate system.
• 6 turns after this Report they reached the the intermediate system, and it was better than we'd hoped: it was guarded by a Space Monster (not the Guardian!) which our ships easily blew away, so we landed the Outpost Ship on a planet to provide a ready-made Marine Barracks when we colonize it (we're currently a Dictatorship, so the Barracks will speed up the colony's development).
• 6 turns after this Report we conquered the first Silicoid system.
• 10 turns after this Report we conquered the Silicoids' homeworld.
• 17 turns after this Report we conquered the last Silicoid colony. It took so long because after conquering the Silicoids' homeworld we were desperately short of Transports. We'd been running a large Command Points deficit and had to buy Alien Management Centers from nothing (4 BC per PP, i.e. 240 BC each) because the Silicoids' industrial tech was primitive, so our reserves were rather low. But the conquest more than doubled our empire's population and nearly doubled our income even before we built Spaceports and Stock Exchanges on former Silicoid colonies, so we were showing a profit before we'd finished conquering the Silicoids.
• The Silicoids never fitted their ships with Proton Torpedoes, and never managed to gather a large fleet in one place, not even for the final battle; the most our ships ever faced was 4, and they were destroyed by the first salvo. Most of our conquests were led by 1 Battleship, while the others guarded earlier conquests.

And all this started from analyzing one Races (diplomacy) screen!
