In August Final Fantasy XIV: A Realm Reborn will go in open beta, but as it turns out there are a few caveats to have a chance to play from the first day.
Of course those that took part to the previous phases of testing will be able to participate in the open beta automatically, the same goes for those that registered or will register a beta code before July the 30th at 9:59 PM PDT.
Those that don’t have a beta code will have to register before Monday, July the 22nd. After that date the beta registration site will be closed and won’t reopen until the beginning of the open beta. It’s unclear if everyone that registered before that date (without a beta code) will automatically be invited to the test from day one.
In any case, whether you have a beta code or not, you better hurry up if you want to play from day one of the open beta, or you might miss your chance. You can register here (Europeans go here) and if you have a beta code you can use it here (here if you’re in Europe).
