Publisher Paradox Interactive and developer Fatshark have opened their action game War of the Roses for beta registration.
The medieval multiplayer combat title recently completed a closed alpha. Interested players can now sign up to be a knight in the King's army and defend England by visiting the official website.
Prospective knights will receive a unique URL after enrolling. If five friends use this link to sign up, the referrer will automatically gain a spot in the beta.
