Battlefield 4 gets new downloadable content, but DICE isn’t done fixing the troubled shooter yet.

Dragon’s Teeth becomes available for Battlefield Premium members July 15 and everyone else July 29. It adds four new maps and a bunch of other new stuff to the PlayStation 4, Xbox One, PlayStation 3, Xbox 360, and PC first-person shooter.

“Dragon’s Teeth sees five new weapons making their Battlefield debut in addition to a new unlockable gadget, the ballistic shield,” publisher Electronic Arts detailed in a press release sent to GamesBeat. “Dragon’s Teeth also introduces a new game mode, Chain Link, a twist on the fan-favorite Conquest mode that sees squads battle to link capture points in order to achieve victory. Fans will also get ten new assignments with unique unlocks and a new Battle pickup in the R.A.W.R., a remote-controlled ground vehicle armed to the teeth.”

This is the first new DLC for the shooter since Naval Strike launched in March. Much of developer DICE’s time has become devoted to fixing bugs and stability issues that have plagued Battlefield 4 since its launch last October. Some annoyed fans complain that issues still persist even as EA releases new DLC and plans to launch a sequel, Battlefield: Hardline, this October.

“I want to be sure you all understand that introducing Hardline in no way means we’re done working on Battlefield ,” DICE vice president Karl Magnus wrote on a blog on the game’s official site. “Nothing could be further from the truth. The Visceral team is leading the development of Hardline, while the DICE team continues to drive BF4. We are committed to giving you the best BF4 experience possible.”

Meanwhile, players still complain of game freezes and getting disconnected from servers. DICE is working on the issues, specifically by improving the game’s netcode, which relates to server stability.

“Making improvements to the “Netcode” in Battlefield 4 has been a top priority for us,” DICE stated in another blog post. “Some of the items we’ve been specifically looking at is how to decrease the feeling of getting killed when behind cover and getting killed without initially seeing a damage indicator. The improvements we did were released in June, and we’re looking at testing out additional fixes during the coming months.”

Despite the issues, Battlefield 4 was a huge sales success. It was the fourth best-selling physical game at retail in the U.S. last year. However, it’ll be interesting to see if its problems translate to slower sales for Battlefield: Hardline.

DICE had previously stated that it wouldn’t release any expansions for Battlefield 4 until it had fixed all of its problems, although it’s unclear if Dragon’s Teeth’s scope makes it an expansion or just a DLC pack. We asked EA for clarification and are awaiting comment.
