This is the DeathShrimp AI that was modified to play Return of Rome as an example for everyone to use. Please feel free to use this to build some custom scripts. This was originally made by ES_DeathShrimp in 1999. It uses the alternate constants from the Sample Builder AI in the newly released Return of Rome Expansion.
Extract the AI and Per file into your Program Files (x86)\Steam\steamapps\common\AoE2DE\modes\Pompeii\resources\_common\ai folder- or wherever you have installed your AI folder. Both the AI and Per files are required to be in this folder.
This script is meant to be only an example, and not meant to be competitive. Competition worthy scripts require many more rules to become solid opponents.
