The following intro spot of Doomsday is a condensate of the precedent Doomsday trailer. It's quite well done.
Have a look:
2008: a deadly epidemic breaks out in the north of the UK Infected people were left behind a containmnt wall.
2033: the epidemic is leaking outside the containment area! A team is sent to find a potential cure behind the wall...
Those crazy punks are really colourful!
