The DLC arrived with the name of the Expedition and it brought with it 2 new maps. These were War Games, Runoff and Swampland. Swampland is infested with tall trees as you might expect and gamers can make the most of the environment and take mobility to a brand new level.
Runoff stretches in height but not area and there is an industrial setting. Then there is War Games and this takes place in the training simulator.
The Expedition DLC costs $10 and if you have the season pass its free. The Xbox 360 version of Titanfall is going to come with Expedition.
