Abandon

Abandon, also known as War Games Map_Set/: 505-2 is a Halo 4 multiplayer map.

Overview
Abandon features a three story building in the centre of a dark forest environment, allowing for some long ranged combat but offering more short range skirmishes due to the trees and tight spaces. It features several man-cannons (one in each main structure, and one inside a tree between them) and ramps leading to all levels.

Trivia

 * Inside one of the map's main structures, two transparent containers can be seen holding specimens of an unknown, alien quadrupedal creature in preservative. It is postulated that these creatures are the "things" that resulted in the base being abandoned.
 * One of the map's lifts is located inside a hollowed-out tree and seems to be powered by escaping air from within an organic structure.
