Sequence 3-3: Prizes and Plunder

Optional Missions:

- Use a swivel to kill 3 sailors

- Plunder 20 rum

Talk to your mates by the beach to start this mission. When you're sailing out in the ocean, use the spyglass by pressing RB to look at any enemy ships. This will reveal the ship's type, nationality and cargo. You can also tag a target ship so you can easily locate it.

When locked to the target ship, speed up and get into attacking range. Your ship has different types of weapons, each with their own strengths and uses. Keep attacking the target ship until it becomes critically damaged and paralyzed. Position your ship beside it, then hold B to board. During the boarding process, you can release steering wheel and use the swivel gun.

For the optional objective, you have to hit and kill 3 enemies using it before hopping aboard the enemy ship. Take out the required number of opponents to successfully complete the raid. Just keep doing this until you reach the required amount of cargo. The second optional mission requires you to collect 20 rum which should be an easy task as long as you plunder ships repeatedly.

Once done, head back to Salt Key and grab an intermediate hull upgrade from the harbourmaster shop to complete the mission. You can also take your time to collect all collectibles and complete all activities while you're still in Salt Key Bank.
