There's an update coming for Battlefield 4 next month that will offer core gamelpay improvements, with soldier movement in the game getting a tweak as well. DICE says that it is tweaking the soldier movement so that it "closely matches the one in Battlefield 3, but without compromising the visual fidelity".
The developer has also said that the changes will make it easier to get yourself out of "undesirable firefights". The new update will also see a refresh to the HUD of the game, which will, from September onward, "only show what is important". Players will have more options to select what they want to see, or not see during the battles in BF4.
DICE is also doing some work on the vehicles, weapon balance and making reviving another soldier a little easier. The new update will see a players defibrillators paddles make a sound when they're fully charged, and ready to revive a teammate. The developer has also promised improvements to the Rush, Obliteration, Obliteration Competitive, Capture the Flag and Carrier Assault game modes. The new update is expected sometime next month, but between now and then, if you don't own the game, enjoy a week free thanks to Origin's Game Time.
