Don't worry, we are just as excited for Fallout 4 as you are. But that doesn't mean that the trailer has no problems! Check out this video to see what's wrong with it. And yes, we ripped off Everything Wrong With.
First, we see Edward Kenway open up a treasure chest with an invisible sword.
Later we see Edward Kenway boarding a ship and fighting. While being attack he grabs hold of an invisible ledge then clips through the ship. He then swims around the inside the ship and is trapped inside the boat.
