E3 2013 - Battlefield 4 Hands on and more game details

Given the increased focus on naval combat, DICE is making sure you aren't a sitting duck if you lose your sea vessel or parachute into a body of water. Soldiers can now swim sprint, use sidearms in the water, hit the crounch button to dive underneath the surface of the water, and even deploy C4 to take out boats.
