Shooter Medal of Honor: Warfighter bears similarity to Battlefield 3 in that it's built on the Frostbite 2 engine. Now there's another parallel to draw: it will use Battlelog.
Battlelog, if you've been living under a rock, is a web service that tracks stats, sports a server browser, connects you with friends, and does a bunch of other things. Reception to it at first was icy, to say the least, but it seems to have grown on most people, myself included.
Warfighter launches in October; pre-ordering it gets you access to the Battlefield 4 beta.
