# Archetypes and Behavioral Logic

Every agent is born with an assigned behavioral core known as an Archetype. This functions as the AI’s personality and dictates how it perceives tactical situations during autonomous PvE missions. An agent’s archetype defines its natural tendencies—whether it acts with aggression, caution, or strategic calculation. This underlying logic ensures that every agent possesses a unique character, making the path to victory dependent on how well the user aligns their unit's inherent tendencies with the chosen training grounds.
