Well, here is the sneak peak for Skyrim Dawnguard! I think this may be a HUGE expansion into a realm with vampires. Yes, I said it, vampires. From what I gather, you can either become a vampire, or fight them.
If you become a vampire, it looks as if you gain minimal flight, plus the ability to change into a half bat. I have to say, I am excited at the prospect of becoming a bloodsucker... again. This time, a crossbow, a whole new world, and a new adventure await.
Here is a link, to watch this on YouTube. As things come in, I will post more information. Remember, the XBOX 360 gets first crack at the DLC, so everyone else needs to just be patient!
Have fun, and keep gaming!
