"You heard me bloody vampires... Yes, I'm calling you all vampires since we all know the world has secretly been taken over so Rayne can kill us quickly. Anyways, if you haven't heard the news BloodRayne: Betrayal will be on PSN 9/6 and XBLA 9/7! Yes, I'm totally stoked on getting to see her again. So many thoughts go through my mind when I think of Rayne. No I'm not being bad but hey you need to go to the older games and you'll think what I'm thinking.
I've played nearly every version of the game and now that she's back this will be one fun adventure filled with blood and more. Don't take my word for it until you play every version of Blood Rayne out."
