With the Battlefield 2042 release date being delayed to November 2021, EA reportedly informed a number of retailers about the delay ahead of time. A slide from that presentation EA gave has seemingly leaked which details each of the main modes within the game, including All-Out Warfare, which is apparently getting Limited Time Modes.
The slide details the three core experiences Battlefield 2042 will offer, including All-Out Warfare, Hazard Zone (which we know very little about), and Portal. The aforementioned All-Out Warfare section is the traditional Battlefield experience we all know and love. This mode is described as including the game modes Conquest, Breakthrough, and LTMs.
