New content for Halo 3 is due to launch on Febraury 2, 2010 in the form of three multiplayer maps available previously only on the Halo 3: ODST multiplayer disc.

The release of the Mythic 2 Map Pack brings the total number of Halo 3 multiplayer maps to 24. The game add-on includes the maps: Heretic, Citadel and Longshore.

- Heretic brings players to familiar ground as the Halo 2 arena Midship returns in Halo 3. The stark interior of the Pious Inquisitor might appear austere on first glance, but Heretic’s symmetrical spaces require players to execute complex strategies in order to outplay their opponents.

- Citadel may be a long abandoned Forerunner stronghold, but its small, symmetrical confines are far from secure. Two opposing bases offer little safety for players looking for solace. Instead, Citadel forces small squads to stay in constant communication, keep their heads on a swivel, and be prepared to adjust combat tactics in close quarters.

- Longshore lacks the commercial ships that once made it a lucrative port for Old Mombasa, but it still bustles with activity. Designed for large-scale combat and well-suited for smaller affairs, Longshore’s multitude of industrial buildings, elevated walks, and open inlets conspire to create a complex battleground tailored for multiple combat scenarios.

Mythic 2 Map Pack will be available on Xbox LIVE for 800 Microsoft Points. Mythic Map Pack 1 and 2 are also included in Halo 3: ODST, which includes the complete Halo 3 multiplayer map collection, an all-new campaign and the incredibly popular cooperative experience, Firefight. Halo 3: ODST will act as a key to the upcoming Halo: Reach multiplayer beta which goes live later this Spring
