That was the trailer for forthcoming LARP series, The Battle of Burgledorf. On their MySpace, they describe the show as:
During a routine Graveyard shift at the local Super Gas station employee Erik Matheson is thrown into the middle of an underground war - disguised as Live Action Role Playing - filled with mighty heroes, mystical creatures and magic…
After meeting a young woman fighting to save a small stronghold called Burgledorf, Erik embarks on a quest to find a magical weapon that is said to wield the power to end the war and bring peace to the world.
With the help of a lonely Wood Elf, a Dwarf named Stump and the local guild of hardcore gamers Erik will discover a greater evil more perilous than the war at hand, and realize that he must make a final stand in order to save the world from being obliterated by chaos.
I am not sure how good the series will be and they have not announced any schedule for release other than Fall 2008. The trailer is high quality, and I am interested. There isn’t much information on either, but if you want to you can check out their MySpace or Website.
