UPDATE: DICE has published an update on its work to improve the state of Battlefield 4 across multiple platforms.

In a post on Battlelog today DICE said it hoped to get an update for the PS4 version out early next week.

"We are aware of the frequent crashes in Battlefield 4 on PlayStation 4. We are hard at work identifying these issues and are hoping to get a game update out early next week. Stay tuned for more details as we can confirm them, and thanks for your patience!"

An update for the Xbox 360 version is undergoing final testing, DICE added. This will be set live soon.

And a new update is in the works for the PC version "aimed at fixing a number of remaining issues in the game". There's no estimated time of delivery on that one, though.

ORIGINAL STORY: The weekend just gone was a busy and troubling one for Swedish developer DICE as it fought against a number of Battlefield 4-related issues.

First up, the PC version of the bombastic shooter was assaulted by a distributed denial-of-service attack (DDoS attack), DICE said, which resulted in the game being unplayable online for much of the weekend.

On Saturday evening embattled producer Ali Hassoon - aka Striterax - took to the Battlelog forum to explain:

"Hi guys, we are being targeted by a DDOS, but working on fixing it asap. I'm sorry somebody is ruining your and my day. Rest assured we are doing our best to mitigate the situation though."

Then, following complaints about crashes and instability in the PlayStation 4 version of the game, which launched in North America on Friday alongside the console, DICE announced it would issue an emergency server.

"We are deploying a new server to the PlayStation 4 platform," Hassoon posted, again on the Battlelog forum, on Sunday, "you might be disconnected from your session as servers are restarting to apply the new patch. The server update addresses a very severe crash issue on the PS4."

DICE's efforts over the weekend do not appear to have satisfied some angry Battlefield 4 players who are still suffering issues with online play. The Battlelog forum is packed with complaints, and some are now calling for PS4 players to be issued with free upgrades to Battlefield Premium by way of compensation.
