To complete this challenge, players are required to kill the Bosun without destroying any of his shield regenerators. There are four Bosun's Shield Regenerators around the room that will constantly charge the Bosun's shield until destroyed. In order to complete this challenge, players must destroy his shield expeditiously. However, since the shield regenerators recharge the Bosun's shield at a very fast rate, players will need a considerably strong weapon to get the shield down. One effective strategy involves the use of a shock weapon which would effectively deplete the Bosun's shield. Another possible strategy is to use the Longnail as its shots will bypass the Bosun's shield, inflicting damage directly to his health.
