Crash Site is essentially two circles that intersect on each other. The central lane that goes underneath the main wreckage features side paths that go into a cave system and into the vessel itself. The two furthest sides of the map are the hangar/ command deck of the MacAllan and an IMC encampment investigating the wreck.
As of Monarch's Reign, the map has since been updated by Respawn to address negative player feedback concerning the map; this includes the addition of eight Ziplines, alongside over 100 miscellaneous terrain changes for ease of movement and the addition of new wallrun sites.
The map reappears as a battleground in Titanfall: Assault, unlocked at account level 2. It is presented in the shape of a loose S, with bits of ship debris making up parts of the wall around the central point. The map has two main features:
There are two Ziplines that Pilots can use to traverse the map, one on each border of the map. This allows Pilots to slip behind enemy lines and immediately threaten the Hardpoint next to the enemy base.
After two minutes elapse, the ship debris in the walls around the central point collapse, the gap providing a new, more direct pathway through the walls towards the bases. Titans can be deployed within this new gap.
