Sometimes “deluxe” or “collector’s” editions of games come with useful things, like codes to unlock exclusive in-game content. Sometimes they have less useful things, like mini lockers for storing your games or Batarangs for bludgeoning your co-workers.

And other times developers just go completely insane and throw in the most expensive, non-gaming related object they can find, like fully functional night-vision goggles. What?!

Infinity Ward has posted a video detailing what will be included in the “Prestige” edition of the upcoming Modern Warfare 2, and along with the things you would expect – an art book you can “scroll through” (too much time developing video games, eh?) and a token for a free download of the original Call of Duty – is the aforementioned NVG headgear, complete with alternating modes and the Modern Warfare 2 logo… which you won’t be able to see… because it will be dark when you’re using them.

The Prestige edition will also include a foam head to put them on, if you don’t feel like using your own. We look forward to blinding ourselves by trying to use them while playing the actual game. Night-vision goggles as a collector’s-edition bonus; the video-game industry is never short of surprises.
