Titanfall DLC made free on Xbox One, Xbox 360 and PC
UPDATE: Will remain free forever.
UPDATE 13/3/15 5.04pm: Titanfall's DLC will remain free indefinitely. When asked how long this promotion would last, an EA representative told Euroagmer "There are no time constraints for the Titanfall DLC offer."
Respawn CEO Vince Zampella recently praised Evolve for giving players free maps and expressed interest in using a similar model for its upcoming sequel.
UPDATE 11/3/15 9.30pm: Titanfall's three map packs are now free to download on PC, as well as Xbox 360 and Xbox One.
Developer Respawn has also now formally announced the offer, which is designed to celebrate the game's one year anniversary of release.
"In celebration of our one year anniversary, all Titanfall map packs are now available for free on Xbox One, Xbox 360, and PC," Respawn boss Vince Zampella announced in a new blog post.
"Thanks again to all of you who've supported us and we can't wait to make more games for you in the future. In the meantime, if you haven't tried the new maps, we hope you love them and happy anniversary, Titanfall!"
ORIGINAL STORY 11/3/15 9.05am: Titanfall's range of DLC is currently free to download on Xbox 360 and Xbox One.
You can nab the selection in one go via the Xbox One season pass option, or download its contents separately on Xbox One or Xbox 360 - that's the IMC Rising, Frontier's Edge and Expedition packs.
Head to the Xbox Games Store website to queue up your downloads.
Microsoft and developer Respawn are yet to announce the offer, which went live overnight.
Fans have speculated that the listings may be a mistake, although the sale timing could also be related to the game's one year anniversary.
Titanfall launched for PC and Xbox One a year ago this week, and a month later for Xbox 360.
"In its current form, Titanfall is perhaps more of a step forward for shooters than a giant leap," Dan Whitehead wrote in Eurogamer's Titanfall review. "But that still represents the most positive momentum seen in the genre for at least five years."
