Battlescreen won't work on PS3 or Xbox 360 versions of Battlefield 4, Battlelog Assistant Producer Jesper Nielsen tells Engadget. Battlelog for Battlefield 4 includes a Battlescreen feature that populates the player's current, live map on a tablet, smartphone or PC – but only when playing the game on Xbox One, PS4 or PC.
"Battlelog is powered by the web, and that has a lot of implications," Nielsen says. "There are a lot of different things you can do, things you can do faster, rather than building stuff in native code."
Battlelog for Battlefield 4 will feature regional leaderboards, will allow players to build weapons loadouts on a secondary screen before starting the game or during wait time between deaths, and will let players change servers mid-game, alongside the standard stats readings.
