OutPost Sequel in the WorksMeh
Admittedly not as good as The Bunker but The OutPost which starred Ray Stevenson ( Punisher WarZone ) was a fun take on the zombie genre. The original film saw those dirty Nazis play with mad science and result in a nasty little zombie outbreak. The sequel is being written by Steve Barker according to Quiet Earth.
