Bungie’s confirmed the patently ridiculous fact that more than 10 billion Campaign kills have now been made in Halo 3.
The “milestone” has been reached in 565 days.
That means 17,500,000 Covenant have been killed daily since the game launched. That’s 730,000 killed per hour. Or 12,000 Covenant troops killed per minute.
Baffle yourself more through the link.
