The initial plan is for a three content packs of DLC that will make up the Titanfall Season Pass. The Titanfall Season pass will set up back $24.99. The content packs will be of course sold individually as well and that will cost you $9.99 per DLC pack.
The Titanfall content packs will of course contain new maps, but while Respawn knows that the packs will contain additional content, it is not yet known what additional content will make up the release. Additional information about what is going to be included in each pack release will be coming closer to then each pack is released. There is no word yet on when the first DLC pack will arrive.
EA also confirmed today, that the Season Pass for Titanfall would be coming to the Xbox 360 as well, meaning that Xbox 360 owners will get the DLC content that is coming to the Xbox One and PC.
In addition to the news about the DLC packages, EA also announced that an exclusive Titanfall digital Deluxe Edition was available for pre-order on Origin. The Deluxe Edition includes the game and the Season Pass for the low price of $79.99. Those that already have it pre-ordered on Origin and want to change the pre-order to the Deluxe edition should contact Origin customer service.
