"It is a proprietary technology that allows you to hear your enemies from further away, giving you a distinct tactical advantage in combat."
Try using that Scout mode in Battlefield 3. Sure I can hear a tank clanking around from far away. I can pinpoint gun shots accurately. I can hear grenades bouncing around and bullet strikes (a bit overwhelmingly confusing at times) in Metro's enclosed area.
everyone's using rubber shoes in BF3! What's use is a Scout Mode in a game that disabled footsteps in multiplayer?
