Respawn's community manager Abbie Heppe has suggested that there might be a Titanfall beta on the cards.
The game is currently enjoying a closed alpha and a fan reached out to Heppe on Twitter to ask about the possibility of an open beta:
@_SEB_73 it's possible

Although the alpha is supposed to have been regulated pretty tightly, some snippets of footage have escape onto the internet, and ytou can catch them below before EA take them down.
