+rampant--printBaseUpgrades=Print to console when a building is upgraded by the AI. These should not happen during a migration, but over the lifetime of a enemy structure.
 rampant--max-base-mutations=Requires Rampant new enemies to have any affect. This number represents the number of times a regional faction group can mutate into other factions. Regional faction groups adapt over time typically to a faction is strong against the type of damage they are being killed with. Death threshold for mutation is based on evolution. (3000 Deaths:<50% Evolution, 4500:<70%, 6000:<90%, 7500)
 rampant--baseDistanceModifier=Modifies the distance between factions as a percentage change. Low percentages may impact performance.
 rampant--printBaseAdaptation=Display a message to the chat console when a faction mutates based on the number of enemies killed
