Capcom opened European signups for the PS4 beta of Street Fighter V, that was mentioned at E3.
If you want to apply, all you have to do is to head here, select your country, log into the PSN, and you’re done.
We don’t know how long applications will be open, so you might want to hurry. Unfortunately, if you live in the Americas, you can’t sign up in the same way, but you actually have to pre-order the game to get access (selecting your country in the link above will let you know where). On the bright side, you’ll have guaranteed access.
