Dead Space Downfall is an animated horror movie based on the Dead Space 2 video game by Visceral Games. I liked the movie, but the ending sucked, and Isaac Clarke isn't the main character. However, it still features grisly, scary necromorph chaos. I think a lot of people will enjoy it, but a non-animated movie would be better I think. To find out more, go to the link below.
