Persian Invasion is a modification for Rome - Total War 1.5 that begins in 490BC. The vast Persian Empire celebrates a golden age of prosperity, and looms over the smaller states that surround it. The king of Persia, Darius the Great, is a tolerant leader, but he has not forgotten what happened in Ionia, and may yet seek revenge for Greek treachery...

A small patch for Persian Invasion Complete Edition.


  • fixes Gerrha recruitment errors
  • all factions given families (to limit early faction elimination)
  • some cities upgraded
  • adds new units Heavy Spearmen and Noble Cavalry to Gerrha
  • adds new unit Peasants to Dahae, to round out their roster
  • tweaks some unit costs/stats
  • new splash screen

Please follow these instructions for installation:

  1. extract the downloaded file, you will find a file named "data"
  2. open up your main Rome - Total War folder
  3. click and drag the data folder you extracted into the file named "PI"
  4. when asked to overwrite files, select 'Yes to All'
  5. open the PI folder and run campaign_map_reset (double-click it, a screen will pop up for just a second
  6. if you do not have the campaign_map_reset program, then open up PI/data/world/maps/base and delete map.rwm, and then do the same in PI/data/world/maps/campaign/greek

One other thing, please make sure that the shortcut you use for PI has the following listed at the end of its shortcut path: -show_err -mod:PI -nm
Also, I strongly suggest that you disable the auto-save function to try and avoid corrupted save-game files. To do this, open prefences.txt inside the PI/preferences folder, find the line AUTO_SAVE: and change TRUE to FALSE.
That's all, the patch is now installed. I do not believe that it is save game compatible.

EmpireOfKerdistan, simply read the 'readme'. You have to extract the files and then you put the extracted files in the PI map. :)
