With Titanfall due March 13th on Xbox One and March 28th on Xbox 360, the inevitable season pass will be available to purchase for £19.99 ($24.99) and will save you approximately, a paltry, £3. The season pass contains 3 map packs that will be dropped throughout the year. That said, a £19.99 Season Pass is a hell of a lot more reasonable than the massively inflated price of a Call of Duty Season Pass (currently £34.99 and officially more expensive than you can pick the game up for).
Other than all the maps included in the DLC, EA and Respawn have yet to declare if you will get anything else with the season pass;
“Each content pack will contain new Maps. All other content is still to be determined and will be announced as we get closer to their release.”
In an interview with Gamespot, Vince Zampella did state that there would be free updates throughout the games lifecycle, features that have yet to make it to the final cut of the game, “We’re going to do paid DLC. We’re also going to do free updates. There are things that we want in the game that we didn’t get to ship in the final game. So we’ll add private matches and things like that for free.”
For PC gamers you can get your hands on a Digital Deluxe Edition of the game exclusively from the Origin store, that includes a copy of the main game and the season pass for £59.99 ($79.99). Although (so far as we know) nothing extra has been bundled with this edition.
