French Publication, Xboxygen, claims a source from retailer Zappos tells them the Titanfall beta runs for all players on February 14 to 19. Other countries can gain access to the beta through Gamestop retailers.
Xboxygen grabbed a few photos of posters indicating the beta start date. The beta will be available on multiple platforms including the Xbox One, Xbox 360 and PC. Respawn and EA sent out alpha invites to players earlier this month, but also required players to sign an NDA which holds players responsible should they share any game details with the public.
Respawn never ruled out a Titanfall beta and often mentioned it was still "possible." Titanfall launches on March 11 for the Xbox One, Xbox 360 and PC alongside a Limited Edition Titanfall Xbox One controller.
