Titanfall's Season Pass content is currently available to download free of charge on the Xbox One and the Xbox 360, according to listings on the Xbox Games Store.

Today marks the one year anniversary of the launch of Respawn Entertainment’s multiplayer first-person shooter. Its release was followed shortly by a trilogy of downloadable content packs, that were normally available separately for US$9.99 or as a Season Pass pack priced at US$24.99. The three map packs are currently available for free for both systems via the Xbox Games Store as the Season Pass bundle or as separate packs.

Second DLC pack Frontier's Edge offers three maps - Dig Site, Export and Haven - along with a slew of bugfixes, and a new feature called the Black Market. While IMC Rising, the final of the three Titanfall packs, features three maps called Backwater, Zone 18 and Sandtrap.
