Mausoleum is a very large level with various outside and inside areas. Like most Gears of War maps this map is symmetrical with a few subtle differences such as the Torque Bow one end and the sniper rifle at another end with different structures supporting these weapons.
Matches are often drawn out and go on longer than on most levels.
There are lots of power weapon variety, which helps unlock potential opportunities to take down enemies. Grenades, Boomshot, Torque bow, Sniper rifle, Boltok pistol.
The outside areas have plenty of areas to hide away and suprise enemies. Players can quickly disappear if being chased, as you can run around the whole map and running through corridors that a chasing enemy may be reluctant to chase a player down.
