Optional objective: Limit damage taken - 25%
After the mission begins, you will receive a task of destroying four privateer ships. Start off by eliminating two smaller ships and afterwards take care of the others. You need to be very fast about it so that you don't get too much damage. Heated shot and hull strength upgrades will make it much easier.
When a circle appear on one of the ships, shoot it with the swivel gun and you will quickly sink the enemy.
