This remarkable little short film acting as a trailer for the upcoming game Dead Island is gruesome - be warned.
That said, it is a cinematic trailer for a zombie close combat FPS and the gore is part of this form of the genre. The video is so much more than that though, it is a haunting, emotional time distorting glimpse of the brutality that such events would bring to people and their family. The production (by Axis Animation) is full of class.
Again, gore warning, but a superb piece of work.
We have been thinking of playing Left 4 Dead 2 - getting some Coop gaming going.
