AI Awareness

Alien AI uses four awareness states:

Idle → Alerted → Combat
          ↓         ↓
        Search ← lost sight
          ↓
         Idle

Idle

The alien remains in place. It does not move toward the map center or use hidden player information.

Alerted

When another alien shares contact, the unit selects a reachable defensive position and sets cone Overwatch toward the last known contact.

When sight is lost, the unit advances toward the shared last-known cell, uses cover, and watches the search direction. Search duration is configurable on Alien Turn Controller.

Combat

Visible targets use the default combat evaluation:

  • Melee units path toward an adjacent attack cell
  • Ranged units score weapon distance, cover, high ground, and clear fire
  • AP may be reserved for an attack after movement
  • Units hunker when no valid engagement remains

AI visibility uses the same grid vision rules as the player.
