This AI is designed specifically for Total War maps, and is especially effective as either Norse (aggressive rusher) or Isis (quasi-defensive)
This script requires infinite resources to fight. Without them, it will simply not gather and therefor not be able to fight. it was designed for maps such as TW The Bridge and TW The Colosseum.
Simply extract the files to your ai2 folder (usually C:\Program Files\Microsoft Games\Age of Mythology\ai2). You should now be able to select "ScionOfTotalWar" from the drop down menu.
This AI wasn't designed with difficulty settings. Therefor, Easy/Moderate/Hard is just hard, and titan is just REALLY hard.
Again, Norse is the strongest opponent, followed by Isis. The Greek and Atlantean civs are incomplete and will provide a weak challenge, so if you're having problems beating Isis you may want to fight some of these simpler unfinished opponents for an 'easier' difficulty.
The Norse will flood you with constant units and try to build directly in your base, much like humans do online. In fact it was designed to simulate my strategies.
Please enjoy this AI and remember, it needs infinite resources AND deathmatch mode, otherwise it will not be able to train units. Also it does not research upgrades, hence the need for deathmatch mode.
