Electronic Arts has announced technical updates for various versions of its troubled shooter Battlefield 4.

Updates for the PlayStation 3, PlayStation 4 and Xbox 360 versions of the game were detailed on developer DICE's Battlelog website today. Each is a long list of crash fixes as well as a resolution of the "kill trading" problem, in which players who shoot at one another seem to die at the same time.

Since its launch in October and November, Battlefield 4 has been plagued by technical issues, to such an extent that EA's trading price was negatively affected, prompting an investigation by a leading law firm. Yesterday, a fix was introduced for the game's PC version.

"While millions of players are enjoying Battlefield 4, we are aware that some players are experiencing issues with the game," offered the DICE update. "While some platforms have had only minor problems, others have had more than their fair share of issues. Resolving these is our number one priority."
