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.
