I found this during the prologue while arming the balista. It's a guy in a white robe, with a red sash who split his head open laying on a broken wagon full of hay. you can even see the hidden blade if you look closely, although it is on the wrong hand. Pretty great easter egg if you ask me. (I didn't take this picture)
Anyway, I'm loving the game right now, it's a really well done port, and all that bonus content that everyone gets for free. Not to mention it's only 50$ on the 360. CD Project is really a great developer, they make some great games and treat their customers well I'm really looking forward to what they do in the future.
Anyone see find any other easter eggs?
