The DLC released on PlayStation 3, and Xbox 360 the other day. Did you pick it up? I did and it costed $14.99, but man was it worth it! The bosses were extremely challenging, new spells, new enemies. I got roughly 22 more hours of playtime out of Dark Souls. That's more time out of a $15 DLC then some full priced games. 2011's best definitely has more goodness to offer in 2012. Buy it now folks!
Warning to access the DLC area you need to have beaten: Ornstein and Smough to obtain the Lordvessel. It is REQUIRED!
Please only view the above spoiler text if you have beaten Dark Souls, or beaten the mid game boss.
So if you have bought it, did you like it?
