Have a bunker? Got some food? Use them: Bungie reckons it's about to drop a Halo-related nuke.
The dev tweeted the picture you see above, adding alongside it:
"Just got this mysterious image and word that something big is dropping this week?!"
What it could be is anyone's guess. Could be anything from just a new Master Chief doll to do unspeakable things with to a live action Halo: Reach trailer.
Whatever it is, all we do now is sit, wait and hope said megaton doesn't kill us. Just be careful: April Fool's is tomorrow [Brilliant - Ed].
Bungie is currently working on Halo: Reach, its final pop at the series, for a fall release on Xbox 360, with the multiplayer beta kicking off on May 3.
