The most significant change is the interactive "Levolution" elements, which destroyable areas significantly alter the level's look and playability. Battlefield 4 also brings back naval warfare and commander mode, where an additional player sees the level from an overhead map and gives orders to team members. New playing modes include Defuse and Obliteration.
The single-player campaign follows a Chinese general who overthrows the government and starts a war with the world, prompting the USA to intervene. The player takes on the role of Recker, a faceless soldier who must survive missions in linear levels with numerous enemies to shoot, including vehicle sections and stealth sequences. There is no co-op mode.
