Firebase Ghost

Firebase Ghost is a multiplayer map in Mass Effect 3. It is located in a slum on Benning in the "Earth Systems Alliance Space" zone of the galaxy map. In the campaign, the Galaxy at War mission N7: Cerberus Abductions takes places on this map.

Description
Benning, the nearest garden world to Arcturus Station, is the station's primary food supply source and an important staging area for starship maintenance and repair. This makes reclaiming the planet a key part of any attempt to liberate the station, capital of the Systems Alliance.

Player Notes

 * Firebase Ghost is one of the largest, if not the largest, firebases in the game. The outside areas are fairly wide.  There are also several long, winding hallways.  This has both advantages and disadvantages.  On the one hand, it allows you more room to maneuver and escape from large groups of enemies and/or enemies will very powerful attacks like banshees and geth pyros.  It also allows you an opportunity to attack from multiple directions and flank the enemy.  However, on the other hand, it makes it easier for the enemy to flank you.
 * Perhaps more so than any other multiplayer map, waiting for extraction at the landing pad may not be the best idea. First, there is no ammo dump at the landing pad; the closest is up the ramp on the left.  Second, you will have to deal with enemies attacking you from a practically unbroken ninety degree arc.  This is it harder to prevent being overwhelmed by enemies, especially those with lethal close range attacks. Third, cover is limited, and most of it does not shield you from weapon fire from all directions.  The cover that exists is only waist high so enemies can shoot over you cover from high ground.
