Forget about all of that free-running nonsense, Assassin’s Creed IV: Black Flag looks like it’s going to be at its best when you’re engaging in combat on the ocean. This brand new video shows piratical protagonist Edward Kenway enjoying a spot of water-based warfare, as he takes down a couple of enemy boats and a fortress in the process.

Capturing these strongholds will not only allow you to construct custom defences against opposing ships, but will also open up the map and unlock new side-missions and more. This, of course, will allow you to further level up your boat, and transform it into a true nautical nightmare.
