In Andrée Wallin's short film State Zero, you know things are going to hit the fan and that the mission will go south, but you don't know when. The world Wallin creates is mysteriously dead and the fear in the characters is real so you know it will happen soon, you just have to enjoy the tense ride until it's done.
A lot of the effects in the short are nice and I'd love to see more of post-apocalyptic Stockholm. Here's some background:
In the near future, the capital of Sweden has turned into a post-apocalyptic wasteland. we join four soldiers on a routine mission in 'zone 3', with the assignment to investigate an old surveillance tower that just went offline.
