Is it on the Xbox Service,i downloaded it from pan and not looked anywhere else
Suprised you were able to get online to download it the amount of times the PSN network goes down, Or did it take you 17 attempts!!! lol.
On a serious note it's an awesome demo/teaser, If the full game is even remotely like this then it's a must buy for me, The trailer does say "this game is a teaser. It has no direct relation to the main title.".
I hope that means that this story has no direct relation to the full game and not the actual look and feel of the game as the look and feel of the game is what makes it so good.
