We were watching this short film called "State Zero" made by Andrée Wallin that is set in the future. What we've noticed that the indoor scenes were mainly done at the The Mall in Reading United Kingdom, which is a favourite indoor game site by British airsoft players. Looks like the props are mainly airsoft guns too... "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. That’s the setting in first-time director Andrée Wallin’s short film.

With Andrées direction, renowned visual concepts and designs, this short film is something extraordinary. Produced by Claire Fleming, the film was shot in London with an international cast, while all exteriors were shot in Stockholm. With incredible CGI and VFX by Bläck, this looks like an excerpt from a big budget blockbuster."
