I don't know whether anyone else has played with this but I was messing around with Battlelog on my iPad2 (apologies to all the Apple haters out there) and managed to set it up to show a map of the session I was playing. It shows quite a detailed map, with all the friendlies, plus any enemies that are spotted. Really pretty useful in the mode I was playing (TDM) although it didn't help my play. I don't know why but I am significantly worse at BF4 than I was at BF3, any iasnt any good to start with. Very frustrating!

I'm not seeing many people spotting at the moment, which is a pity because it really helps with this second screen full sized map.

BTW ÂÂ*it seems as though to enable this functionality the tablet must be on the same network as my main gaming PC, which must be broadcasting in some manner. Interesting...
