The patch for the PlayStation 4 version of Battlefield 4 schedule to arrive today has been delayed due to a need for additional testing, DICE announced today.

"The PS4 game update that was originally meant to go live Dec. 3 is undergoing some additional testing and will be rescheduled for a later date," DICE said on its forums. "We will get back with final details as soon as we have verification that the update is good to go."

The patch aims to address, among other issues, the Battlefield 4 "one-shot kill bug," where bullets were sometimes applying incorrect levels of damage to a character. The PC patch scheduled for today remains on track, as do the updates for the Xbox One and PlayStation 3 versions of Battlefield 4.
