Verdun is the first multiplayer FPS set in a realistic World War One setting, the game which started the WW1 Game series. The vicious close quarters nature of trench warfare means that skill with a bayonet can be as vital as good aim with a rifle. The game takes place on the western front between 1914 and 1918, in one of the bloodiest conflicts in world history. The developers were inspired by the infamous Battle of Verdun in 1916. The game offers 4 distinct game-modes: Frontlines, Attrition, Rifle Deathmatch, and Squad Defense. There are also many historically accurate features such as realistic WW1 weaponry, authentic uniforms, horrendous gore, and maps based on the real battlefields of France and Belgium. The gameplay in this true WW1 battlefield experience is as immersive and gritty as it can get, with features such as optional realistic gore which portrays the true horror of the First World War and authentic weaponry including artillery and gas. Weapons need to be handled with skill - each gun handles differently and there are no floating crosshairs to aid your aim, along with realistic bullet physics to contend with. Battle your way across no man’s land to capture the next enemy trench line, before switching to defense to protect your gains in the Frontlines game mode. Keep your head down or quickly don your mask in the event of artillery strikes or gas attacks. This unforgiving war isn’t for the faint hearted! Looking for more WW1 action? Check out Tannenberg for Eastern Front maneuver warfare, or the upcoming Isonzo for Italian mountain warfare!
