The new and free update for Battlefield 4, called the Night Operations, will be rolling out on September 1st.
The release was confirmed over at
Battlefield 4 forums and will include the new Zavod: Graveyard Shift map, which is a remix of Zavod 311 map but designed for night battle. It is also important to note that the new map will support all existing game modes in Battlefield 4.
In addition to the free Night Operations update, DICE will also release the new Summer Patch on the same day which should bring plenty of improvements and tweaks.
Battlefield 4: Night Operations for European Playstation consoles will be coming a week later, on September 8th.
