Sign-ups for a chance to participate in beta testing for War of the Roses multiplayer combat beta have been opened to the public.
From Paradox Interactive
Starting today, players can enroll to be a Knight in the King's army and help restore order to England by visiting the following link: www.waroftherosesthegame.com
When signing up to guarantee their access to enter the beta, future knights will obtain a unique referrer URL from the King that can be shared across social media channels. When five friends use this player-specific link to sign up for the beta, the player who is linked to the URL will be granted a secure spot in the beta.
