Having played the 1st game to death I have been looking forward to the second game and it seems it will not disappoint.
The demo itself lets you get a real feel for the game and certainty leaves you wanting more. So if you have not played the first game, grab the demo and see what you have been missing and i'm sure you will have this game on pre-order soon.
Demo fun: You have 30 mins to play the demo. Once the timer hits 1 second hit the Start button. Now repeatability hit the Xbox button and the A button together. The game will briefly unpause and jump back into the guide.
As you do this look for the 1 second to flash up on the collar on your characters picture, once its hits 0 or the screen goes black for a few seconds unpause and play on for as long as you like without a timer. (Just dont die!)
You can also explore the entire map. To remove the nag screen change the HUD transparency levels in the menu. :)
