In a PR stunt of epic proportions, Microsoft and 343 Industries transformed the Principality of Lichtenstein into a Halo 4 fantasy world for press and "super fans."

Attendees of the event travelled to a top-secret location before being thrust into a war zone, and at some point they even got to play the game. Imagine that!

The 13th-century Gutenberg Castle was transformed into a military fortification, a working quarry was turned into an arena, the countryside played host to a military camp, and fifteen actors—including one playing the Master Chief himself—played out a two hour-long adventure.

Check out the pictures above. Are you looking forward to Halo 4?
