DICE has revealed more details about the next iteration of its social tracking service Battlelog for Battlefield 4.

The service can now sit on your mobile or tablet device while you're playing, acting as a second screen that shows information on the map and allied player positions.

Players can also use their mobile device to customise their loadouts, browse servers, and see the status of their friends.

Other features include new regional leaderboards, which allow players to see who is the best player in their local region. Players can also set up their own custom missions between friends, with DICE setting up challenges to see who can blow up the most enemy vehicles in a round as an example.

DICE introduced Battlelog alongside 2011's Battlefield 3, with the social service designed to keep track of players' activities and achievements within the game. The PC version of the game is launched directly from Battlelog itself.

Battlefield 4 will launch on the PC, Xbox 360, and PlayStation 3 on October 29, with Xbox One and PlayStation 4 versions also in the works.
