bs angel announced in this week’s Halo Bulletin that 343 Industries will be showing off the Halo 4 Majestic Map Pack in a live stream event tonight, (Sunday February 24th at 2PM PST - 10:00PM UK) 
The stream will feature designers and other 343 team members playing FFA (both Infinity Rumble and Rumble Pro) and 4 vs. 4 matches. There will also be a chance to win Majestic Map Pack codes during the stream – that's right, you could get your hands on the new DLC before it’s officially released!

I'll look forward to seeing you guys there!
