Sony Pictures movie 30 Days of Night will be soon released in theatres but the site is, of course, already live to start frightening viewers wannabe. Created by Big Spaceship, one of the best agencies in creating movies' related online experiences, the site is scary enough to build curiosity around the film.
Gaming plays a pivotal role on the site, with a "simple" single player shoot em up and a more complicated (but engaging) multiplayer "kill em all" advergame in which players' tasks change every day.
Big Spaceship's work on the multiplayer game looks impressive. Unfortunately I haven't been able to test it... in a multiplayer game "by definition" you need someone to play with (or against) and visiting the site from Europe at 10 am in the morning I couldn't find anybody to challenge.
