The latest trailer for Assassin's Creed 4: Black Flag gives us a developer's perspective on the tools Kenway will have at his disposal when sneaking about and eliminating enemies.

Game Director Ashraf Ismail guides us through this playtrough, showcasing a bit of the underwater elements, as well as the sneaking and assassination content. You'll also get a better look at some of the upgrades coming in AC4, including the revamped Eagle Vision, which allows you to tag and target enemies through walls.

There are also new techniques and tools you'll be able to use, such as the hiding door (a new way to hide dead bodies), and the berserk blowpipe darts, which cause enemies to go a little crazy. Black Flag looks to be running pretty smoothly in the video, and the next-gen version certainly looks stunning.

Check out the trailer to see how the mission turns out, and let us know what you think of the all-new Assassin's Creed.
