No one knows what will get you in
Respawn's gearing up for its big February 14 beta for Titanfall, but no one really knows yet how to get into it. In the past, many high-profile games have handed out their beta invites to people that pre-ordered. That won't be the case here.
According to studio founder Vince Zampella, you don't need to pre-order Titanfall to gain entry to the beta. Besides that tidbit of information, Zampella remarked that some things have to be approved before he can announce any more details.
It's rumored that the beta will be exclusive through GameStop in the US and Zappos in France. If that's true, these may go out to members of their rewards clubs, or something similar. The only thing that is known is that February 14 isn't very far away, so we won't have to wait long to find out.
