The video had been leaked earlier on Tuesday, but EA had it removed quickly. The official game launch and trailer debut took place later on Tuesday night at the Game Developers Conference (GDC).
Strangely, Amazon.com says the game will reach retail on Dec. 31, 2013, but the trailer video and EA say the game is due out in autumn.
The trailer, called "Fishing in Baku", opens with a rendition of Bonnie Tyler's classic song "Total Eclipse of the Heart." Viewers then watch the game's protagonist, Recker, as he shoots his way through the mission map.
EA Games EVP Patrick Soderlund promised that Battlefield 4 will be the best looking entry into the series ever, thanks to DICE's proprietary Frostbite 3 engine.
To be this early in development, and to already be so polished is a huge achievement for the DICE team and reflection of their passion and commitment to driving the franchise forward. Today's demo was just the beginning -- we have so much more in store.Those who pre-order "Battlefield 4" will receive a free "premium expansion," but EA did not elaborate on this add-on. A "Battlefield 4" Digital Deluxe edition for the PC will also be available, exclusively through Origin. Gamers who pre-order this version will also receive the aforementioned expansion, as well as access to the "Battlefield 4" multiplayer beta.
