Call of Duty 4: Modern Warfare is about to start its public beta test on Xbox Live, an engagement that has Xbox 360 owners volunteering their gamertags and repeatedly running into a hail of online bullets for the sake of research. According to an Infinity Ward posting on the official forum (registration required), information on the sign-up process will be posted on the Charlie Oscar Delta site today at 5PM PST.

The message notes that the program will roll out in several waves -- the first to be drafted could be playing the World War Now shooter as early as tonight. Read our impressions of the game's multiplayer aspects if you're not convinced this CoD is worth reeling in.
