Up to 64 players can participate in the realistic, tactical squad-based Game Verdun, which is set in the trenches of World War I. (with 32 on each side). 
Depending on the country and type of squad chosen, squads are typically made up of four players, each of whom plays a specific function and serves as the squad leader, known as an NCO. By assisting the team, such as by killing adversaries or taking over sectors, squads can Level up and receive new skills and improvements to their existing ones, such as accuracy and suppression. The squad's kind and name are both changeable by the NCO. 
NCOs can access support tools like mortar rounds, artillery shells, creeping barrages, white phosphorus strikes, smoke screens, and artillery barrages. Additionally, they have the option to summon more passive skills that will enable their squad members better withstand enemy suppression or enemy recon. NCOs can frequently be seen carrying martial weapons like sabres and trench clubs in addition to a self-loading pistol or revolver. Depending on the type of unit and the real-world availability of those kinds of weapons to them and other factors, the other members of the squad frequently use a variety of bolt-action rifles, a variety of bayonets, melee weapons, grenades, revolvers, semi-automatic rifles, machine guns, and SMGs. 
By abruptly bending the camera view to mimic a soldier dodging bullets or reacting to almost being shot, suppression has an impact on players' aim and vision. Bombs and artillery also suppress the player, making it more difficult for them to maintain a steady drive while being fired upon. Players can crouch, lie flat, and climb up the trench parapets to observe and shoot at oncoming opponents. In between two sectors, environments typically include many craters created by small artillery but no cover.
Frontlines, Attrition Warfare, Squad Defense, and Rifle Deathmatch are the four Game modes.
 
Modes of play of Verdun
 
Frontlines 
The Central Powers and the Triple Entente, the two historically significant sides in World War I, are available for the players to join. Each side contends for control of a frontline map with various sectors that either side can take in a turn-based battle. The player will be required to defend each captured sector of trenches since, in keeping with the traditional attrition warfare of the era, both sides will attack and counterattack one another in turns. To win in Verdun, you must either take the enemy's headquarters sector or score more points than the opposing team. A sector can be taken in an attack or retaken in a counterattack to earn points.
 By dying as little as possible and moving as many people as possible into the enemy sector for as long as possible, players must keep an offensive moving forward.
 The adversary launches a counterattack on their sector in response whenever an attack on an industry loses momentum, which occurs when too many teammates die or fail to reach the industry. Unlike Tannenberg, where both teams must conquer a sector within a given time, there is no set quantity of tickets for both sides to use.
 
Squad Defense 
 In the cooperative Game mode Squad Defense, players take control of one of the 12 four-person squads and defend themselves against infinite waves of attacks from AI-controlled soldiers. The Frontlines Game mode's available maps can also be used for this mode. The only method that supports offline play is this one.
 
Rifle Deathmatch
 
Players in Rifle Deathmatch engage in a free-for-all conflict while only using one of the firearms and add-ons they can select when they sign up for the Game. In this skill-based Game mode, accuracy and strategic foresight are rewarded. By killing other players, players can collect experience and career points. Players can Level up their weapons with career points, adding new accessories like a bayonet or scope.
