Electronic Arts announced today that its sort-of Second World War FPS Battlefield 5 will go into open beta on September 6, or a couple of days earlier for Origin Access subscribers (basic or premier) and anyone who preorders. Open beta preloading will begin for everyone at 1 am PT/4 am ET on September 3. 

The beta will include the Conquest mode on the Rotterdam map, a street battle in Holland featuring "dynamic physicality and destruction," and both Conquest and Grand Operations modes on the Arctic Fjord map. Grand Operations, which we got a look at in June, is a series of asymmetrical attack-and-defend battles that unfold across multiple stages taking several in-game days.
