There are two new demos available to download on Xbox Live today.
The first is Blades of Time, a game which allows gamers to play with time itself (it's not just a clever title) using Time-Rewind gameplay.
The second is Birds of Steel; a flight sim (and not a game about throwing metal birds at boxes) that gives players a chance to rewrite history in WWII.
For more information on both demos head over to Major Nelson's blog for details.
