The Heroic map pack contains three new maps, each presenting a totally different play style. Standoff’s symmetrical valley, with its entrenched bases and fields of boulders is ideal for mid-sized objective and Slayer game types, while Rat’s Nest’s vast, labyrinthine passages bring something quite new to the Halo multiplayer experience – an indoor vehicle paradise, strongly influenced by the Campaign mode ideal for big team battles. Finally, Foundry is the ultimate Forge map – players can edit every single object in this voluminous industrial warehouse, place stairways, walls, bridges and tunnels to create an entirely new play space and build almost any kind of map they can think of.

Warmly crafted, dutifully beautified update of Halo: CE classic multiplayer map, Chill Out. Love, Bungie

The Legendary Map Pack blends old and new. Ghost Town’s asymmetrical mix of confined spaces and long lines of fire makes for frenetic games. Avalanche re-imagines the original Halo classic, Sidewinder, with new features, tweaked vehicles and massive outdoor spaces. Significant changes bring big improvements to the map, yet its contours and cliffs should provide a welcome sense of familiarity. Blackout, on the other hand, is the purest remake to date – all time favorite Lockout gets a graphical overhaul, but retains its challenging mix of ramps, platforms, tunnels and hallways.

The long-awaited Mythic Map Pack drops into Xbox LIVE Marketplace.

An excavation site surrounded by deadly Forerunner defenses, the mysteries of Sandbox are hidden high above, deep below, and right before your eyes. There are no refunds for this item.
