A few weeks before E3, details on Battlefield: Hardline started leaking, and just a few days ago, EA released an official trailer for the game. At the E3 Briefing, the game was shown off with a full game being played out, showing the new cops and robbers style gameplay, and of course some Frostbite engine destruction.
In addition to this gameplay trailer, EA has announced that a closed beta for Battlefield: Hardline is available NOW. Players can register for both the PS4 and PC beta at the Battlefield Hardline website. The site notes there are a limited number of spots, so be sure to sign up soon to reserve your spot. No beta for the Xbox One has been announced at this moment.
Battlefield: Hardline will be available October 21, 2014 for Xbox One, PS4, and PC.
