Sounds like a good bonus to me.
Last week an image stating that if you pre-ordered Medal of Honor: Warfighter you would get access to the unannounced beta for Battlefield 4 showed up on the Origin store and was quickly taken down. Then today EA made it official by announcing the pre-order bonus via a new multiplayer trailer for Warfighter.
No other details were provided about the beta or anything else related to Battlefield 4, but CVG tweeted earlier that the beta will start in Fall 2013, but nothing official from EA so far. Check out the trailer above to learn more about the multiplayer in Medal of Honor Warfighter and get ready for the beta by pre-ordering it now.
