The Xbox One does not allow you to play online with friends on Xbox 360. If you want to play with friends on Xbox 360 you will need an Xbox 360 console and a copy of Battlefield 4 for Xbox 360...
“Pre-order Battlefield 4 on Xbox 360, PS3 or PC at GameStop to gain access to the Exclusive Battlefield 4 Double XP launch weekend on 2nd - 3rd November 2013*”
But for all of its shortcomings and blatant compromise, Battlefield 4 on Xbox 360 still retains those raw, fundamental workings of the online Battlefield experience, albeit at 30fps. If you can look past its rough, unpolished exterior, there's a great, unpredictable multiplayer package to be found, but only for those who aren't looking to jump into next-gen just yet.
Battlefield 4 on Xbox 360 is a fitting advert for the very real need for a new generation of consoles; developers' ambitions are being restricted by, at this point, frankly antiquated hardware. Visually, it's an eyesore, with overblown lighting effects illuminating the game's plentiful issues with aliasing, screen-tearing and low-resolution textures.
