Blackout

Blackout is the third of the three maps that make up the Legendary Map Pack in Halo 3. It is a remake of the classic Halo 2 map, Lockout. It was called Moonbase Alpha and Space Camp during its development, due to its nighttime setting.

Instead of a Forerunner facility, this map takes place in the Antarctic, on weather station z/41. The layout is mostly identical to that of Lockout, but includes more grenades and equipment. It is also the only Halo 3 map to take place during the night.
