"Halo 4" is a huge hit with gamers.
In the first 24 hours of its release, the game racked up sales of more than 220 million dollars around the world.
Think about it this way.
Last Tuesday's opening beat the record for the biggest one-day opening in U-S box office history, "Harry Potter and the Deathly Hallows: Part 2."
"Halo 4" was developed exclusively for Microsoft's X-box 360.
