Titanfall fans still rolling on the Xbox 360 version can rest assured that updates will still be coming out on a regular basis, thanks to an announcement made a few days ago on the official Titanfall blog.
Bluepoint has been working on the Xbox 360 edition under the direction of Respawn as new enhancements come down the line, such as free updates and paid DLC like Titanfall: Expedition. These updates will "naturally follow" those released for the Xbox One and PC users. The reason being? The 360 edition simply needed more time in the oven after the PC and Xbox One took priority. Once Respawn has polished off improvements for those systems, the Xbox 360 edition follows.
Bluepoint is currently working on bringing over the same content that was included in the Xbox One Content Update 2 (which was divided into two parts) as well as the Expedition DLC. These will be available "soon," but in the meantime check out the Expedition gameplay trailer above for more big bots.
