"Cisalpinia, 63BCE

A long-contested political campaign has seen you appointed by the Senate as proconsul for northern Italy, but the cost of public renovations in your new jurisdictions has left you deeply in debt to your political opponents, who plan to use your financial distress to wipe you out for good. However, new opportunities await - rumours of further barbarian activity beyond the Republic's borders present a chance at martial glory and financial success, which may allow you to return back to Rome ....and CONQUER THE WORLD."

  • Start time: 60BCE
  • Victory conditions: destroy all non-aligned factions. Convert all factions either into allies and vassals, or destroy them to win the game.
  • Gens Julii starts off with no alliances or enemies.
  • Despite being an ally, SPQR hates you a lot but it won't decide on attacking you, unless your total fortification level os 40% of its own. Each time your turn ends, the computer tots your score up against that of SPQR's. If you near the threshold, then the computer will declare war.


Only Gens Julii (with capital based in Gallia Cisalpina) are playable. They differ from normal Romans in that they don't train Syrorum.

Other factions:

  • Roman Republic /Optimates (they assume the Chremonidian bonuses, and have 2 capitals - Achaea and Rome). They differ from normal Romans in that they cannot train Sabelli or Gallorum - see to it that Greek mercenaries are done ASAP.
  • Cantabres - they control only Asturia.
  • Suebi - controls a fairly large part of Germany.
  • Belgae - They control both Caint and part of Bellovacaea
  • Arverni - control most parts of Gaul
  • Ptolemaic Kingdom - usual place
  • Dacia - they rule over two territories in Magna Dacia - Dacia and Getia.
  • Numidia (vassal state to Roman Republicans) - based in Atlas Pontus - a vassal of SPQR..
  • Pontus
  • Bosporans - a vassal of SPQR.
  • Judaea - represented by Carthage. Controls only Judaea, is an ally of the Romans
  • Odrysians - based off Epirotes, uses same architecture.. Allied to Rome and rule Thracia..
  • Parthians - they control the easternmost end of the map.
  • Seleucids - have their base in Syria. They actually don't exist, but only as a rebel faction in the area. It isn't likely that you will be able to kill them instantly.
  • Armenia and Kartli
  • Gens Julii - Romans. All complete.
  • Nabataeans
  • Illyrians - based off Achaeans, but have a different set of units and clearly a different bunch of units.Illyroi are all trained to resist heavy infantry and this is the same for them too.

Factions that do not appear on the map.

  • Sakas - Sakas replace the Bactrians. The cavalry is Partho-Sarmatian.
  • Yonas - they take over from the Bactrians

Factions that retain over their original units?


Tribute cannot be collected from uniting continents - there are no continents to speak of in the Imperium Invictum campaign. You will receive tribute based on 2 different factors:

  • The first is average regional strength, rounded up (a)
  • The second is the number of rare resources controlled by you and your allies (b)
  • the third is the number of allies, (c) and
  • The last one is enemies (d).

Ultimately, tribute is received in the following manner: (a*c)[1+(b/d), rounded up. Thus, for a faction to receive tribute it is necessary to have allies and to fight limited wars, while at the same time gaining rare resources.

Eg: Pontus has 20 regions with a total combined regional strength of 49. For Pontus, (a) is calculated as 2.45. It is at war with both Rome and Parthia, but has Egypt, Suebi and Getae as allies, so (c) is 3, (d) is 2. As for resources, it and its allies control a total of 8 patches, which sets (b) as 8. In total, Pontus' tribute on its next turn is 2.45(3) [1 + 4] = 36.75 , rounded up to be 37 tribute per turn.

So, what this means is that:

  • Diplomacy is vital for survival.
  • Tribute has to be plowed back into your territories.
  • War is a risky business, but peace is even riskier - whenever you fight a war, you will be lowering your total tribute by decreasing your combined regional strength and the number of enemies. However, your allies may also become free riders off your own tribute given their access to your resources, so you need to be careful.

Another assumption: through overruns, Pontus manages to destroy Parthia, but in the process acquires 5 additional regions, 2 of which have resource patches. The result is that (a) is now (20*2.45)+5/25 = 2.16 while d is now rendered as 1. Pontus' per turn tribute is now 21.6(3)[1+10], which is equal to 71.28, rounded up to 72!

Thus, diplomacy has been changed. CPs will now happily accept instant alliances with you only as long as they see you have rare resource that they can use - if you have 5 or more rare resources than they do then they will happily accept trade with you right away.


Most areas of the map do not have supply centres, so playing as Gens Julii you will not find it easy to get sufficient armies for conquest until you have conquered most of them. The main supply centres are as follows:

Of all these supply centres, only the one in Tarraconensis is free, the rest having been taken over by all the other factions,
