Here we go with more solid info from yesterday's X10. Halo Reach, right? You're up for it right? Bungie says it's a risk though. But here's when you get your first experience.
"Starting on May 3, the Halo Reach public multiplayer beta will give you the opportunity to drive the latest advancements in multiplayer gameplay in the blockbuster franchise that started it all on Xbox LIVE. Access to the beta will be available through the Halo 3: ODST game disc on Xbox LIVE."
Yes, indeed, get ODST first though... but you would have done that anyway. Also, put a bet on sales of ODST getting a boost on about May 8th.
