Respawn will be dropping their first DLC pack, Expedition, tomorrow (exact times to be confirmed), along with their latest patch Update.
The Xbox 360 version won't be out until next month, as the 360's development team Bluepoint have to wait until Respawn's finished before they can start the conversion process to the older Xbox console.
The Expedition Pack, which is free to those with a Season Pass, and around a tenner for anyone else buying separately, includes three new maps - Swamplands, Runoff and War Games.
