I'm not sure if this promotion is listed anywhere on their website, but several UberEnt devs have said at different times that anyone who signs up for the Beta today, February 14th, Valentine's Day, will get access. Since it's not a public promotion, details are scarce, so it's hard to say exactly what that means; but it probably means that anyone who signs up today will get in with this week's wave of invites. In other words, sign up today and be playing by Friday! If you wanted to check this game out, now's your chance.
Valentine's Day Promotion! Everyone gets in today!
