Promise you'll play Halo 2600 (that's a covenant we can get behind)

Have you ever wondered what Master Chief's intergalactic adventures would look like if rendered by an Atari 2600? Neither have we -- and now that the folks over at Extra Guy have shared their find of "Halo 2600," we don't have to. Bizarrely, ex-Microsoft VP of game publishing Ed Fries is credited on the game's cover as the creator (as seen on the game's Facebook page).

Halo 2600 was playable at the Classic Gaming Expo in Las Vegas, which came to an end today. Sure, it's playable online right now, but apparently we missed out on 500 real-life Atari 2600 cartridges containing the game (check out a photo of them all lined up). How's that for a limited edition?

[Thanks, Anthony!]
