Battlefield 2042 uses a specialist system instead of a troop system, and each character in the specialist system has its own attributes and strengths. Players can customize their specialist's weaponry, such as primary weapons, secondary weapons, and projectiles, among others.

In Battlefield 2042, there are several multiplayer modes for players, Total War can be said to be the main mode of the game, but in this mode there are two game modes: Conquest and Breakthough mode. These two modes are different from each other.

In the Conquest mode, 128 players are allowed to compete together. And the map in the mode is very large, so the map will be divided into many areas. Each area will have a target point, and the player will only have to defeat the enemies around these target points to take the area for himself. In other words, players will get points for the amount of land they occupy. The enemy's area will be in red and our area will be in blue, and the enemy's and our life bar will be available at the top of the game, when one of them runs out of life bar, it means game over and failure.

When the player takes the area for himself, it does not mean that the area is always yours, because the area can be attacked by the enemy at any time, because the player must pay more attention in this regard. This map is very large, that means the targets will also be very many and suffer from enemy attacks quite frequently. Therefore players need to make a tight battle plan to prevent being sneaked up on by the enemy.

While defeating enemies in the game can also deplete their life bars, the best way to do so is to occupy their territory. The main player occupies more areas than the enemy, then the player occupies a certain dominant role in the game.
