Battlefield 4's Second Assault downloadable content will be released Feb. 18 for Battlefield Premium subscribers on PlayStation 3, PlayStation 4, Xbox 360 and Windows PC, according to a post on the official Battlefield Blog.
The DLC will be available on those platforms for non-Premium subscribers two weeks later, on March 3.
Second Assault contains four maps from Battlefield 3 — Operation Metro, Caspian Border, Gulf of Oman and Operation Firestorm — rebuilt in Battlefield 4's Frostbite 3 engine. It was released for Xbox One at the console's launch last November.
Battlefield 4's third downloadable expansion, Naval Strike, will launch its "water-based combat" in "late March" for Premium members, according to the post. It will contain four new maps, new weapons, new vehicles and more.
Last December, in the midst of a launch in which Battlefield 4 players experienced problems with the first-person shooter on multiple platforms, EA announced that it was halting work on expansions to fix those problems. EA declared February "Player Appreciation Month," offering players daily giveaways and more.
