Microsoft and 343 Industries has announced the Halo 4 War Games Map Pass which offers a 15% discount for three War Games map packs.

The map pass will cost €19.99 (2,000 Microsoft point). The three map packs will be available in December, February and April. Those who purchase the map pass will receive two bonus in-game helmets, as well as a unique in-game emblem.

Below are the details and release timeframe for the map packs:

Crimson Map Pack (December release timeframe)

• Maps: Wreckage, Harvest, Shatter
• Description: Witness the chaos of a clash of civilizations in Wreckage, with its blend of claustrophobic spaces and dangerous exposures and venture into the human colony environs of Harvest, and explore a human foray on an alien moon in Shatter.

Majestic Map Pack (February release timeframe)

• Maps: Landfall, Monolith, Skyline
• Description: Landfall’s emphasis is on infantry battles against a glittering ocean on a distant world, while Monolith exposes you to the naked vacuum of space – and the firepower of opposing teams, and Skyline’s distinctly industrial feel provides new challenges in somewhat familiar, but occasionally confined spaces.

Castle Map Pack (April release timeframe)

• Maps: Daybreak, Outcast, Perdition
• Description: Daybreak is set in a military facility against the backdrop of an idyllic mountain range, while Outcast plunges you into the warrens, canyons and arches of an alien edifice, and Perdition takes players into the heart of an urban sprawl, with tactical speed and situational awareness its key features.

Here is some concept art of the upcoming maps.
