Alan Kertz, the lead core gameplay designer at DICE for Battlefield 4, has revealed that the PS4 version of the game will "likely" use the L2 and R2 buttons for aiming and shooting as they are "so much improved" over the PS3's triggers.

Shooters on PS3 usually default aiming and shooting to the L1 and R1 bumper buttons on the DUALSHOCK 3 due to the fact that many players feel their fingers slip off the controller's triggers although players can often change the control options if they wish – it's not clear if gamers will be able to alter the controller configuration in Battlefield 4.

However, it appears that Sony has taken complaints about their controller seriously and have made significant improvements.

Other changes made for the DUALSHOCK 4 include moving L3 and R3, the sticks, further apart to prevent people's thumbs hitting off each other and of course the sensor light bar which will have different functions based on each game. As part of the changes the Select and Start buttons have been replaced by Share and Options.

The DUALSHOCK 4 will also include an inbuilt speaker.

Battlefield 4 is set to be launched on PS3, PS4, PC, Xbox 360 and Xbox One later this year with the first DLC for the game being a timed exclusive for Xbox One.

The PS4 is also due for release this holiday season and you can have a closer look at DUALSHOCK 4's design and inputs in this developer video.
