Dates for upcoming Halo 4 map packs reportedly leaked out via the German Xbox 360 dashboard. The Halo Council screen captured an advertisement listing the Crimson Map pack as launching on December 10, the Majestic pack on February 25, and the Castle pack on April 1.

The War Games Map Pass is currently available for 2000 MSP and is set to grant access to the three packs, but developer 343 Industries hasn't announced their release dates. We've reached out to Microsoft for clarification on when the map packs are due to deploy.
