Species Location Weapon Abilities The metal jacket is an enemy in Jak II and Jak 3. It is a small, flying, insectoid metal head, closely resembling a wasp. Metal jackets made their first appearance flying through the rift gate in the opening cutscene of Jak II. They were later seen at the strip mine in the mission "Rescue Vin at strip mine" during Jak II. They made a reappearance in Jak 3 in the mission "Find satellite in volcano" at the Great Volcano, where they were then found at the Monk Temple in the mission "Complete Monk Temple tests" shortly afterwards.
