If you want to signup for the Titanfall beta, your time has come: Respawn Entertainment and EA have just opened up registrations for the beta - on both the PC and Xbox One.
Registering for the beta doesn't guarantee you a spot, but it gets you in the running. EA will e-mail those who made it into the beta "no later than 11:59 PM PST on Feb 17th". We don't know what to expect from the beta, but we should see a couple of maps and game modes to play with. You can sign up right here.
