Some watchful German fellow has spotted a number of Halo 4 DLC release dates on the German Xbox 360 dashboard. A little worryingly, two of the map packs in question are named for Spartan fireteams in Halo 4's Spartan Ops mode. Those had better not be Spartan Ops maps in a delightful new guise, Microsoft.
Crimson Map Pack is out on 10th December, while Majestic Map Pack follows on 25th February. Castle Map Pack, finally, is due 1st April. All these are covered by the Halo 4 War Games Pass - individual prices have yet to be released.
What do you want from the first wave of Halo 4 DLC maps? I'd settle for something roomy enough to have a decent Mantis fight on, myself. Ragnorak's losing its charm.
