If you're planning to play the Battlefield 4 beta on PC, you can start downloading the files right now. DICE has opened up pre-loading for the early access beta through Origin.
The early access beta for BF4 will launch on October 1st at 4AM EST. In order to participate, you need to have purchased Battlefield 3 Premium, pre-ordered the Battlefield 4 Digital Deluxe Edition on Origin, or bought Medal of Honor Warfighter. It's being held on Xbox 360, PS3 and PC but only the PC beta offers pre-loading. If you're a BF3 Premium membership, you'll get access to whatever platform your membership is tied to.
The beta allows players to test out Siege of Shanghai, one of ten multiplayer maps that will ship with the game. Domination mode will offer infantry-only, close-quarters battles. In Conquest mode, players will also have access to land, air and sea vehicles. They'll get to see for themselves whether DICE has really revamped naval warfare.
The new feature of Levolution is also on full display here. In this game, players can do more than smash through walls or topple small buildings. In "Siege of Shanghai," they can bring down an entire skyscraper and dramatically reshape the map. Levolution also extends to smaller player choices like lowering shutter gates or raising bollards.
The system requirements for the PC version of Battlefield 4 are below. They're a noticeable step up from BF3's requirements so if you were only barely running the game last time around, you might need to upgrade in order to handle BF4.
