World War One expands to the mountains of the Italian Front - beautiful but deadly in equal measure. Take part in key offensives of the Great War, from the Sixth Battle of the Isonzo to the Strafexpedition, and lead your team to victory among the scenic landscapes and peaks of Northern Italy.

Isonzo is a realistic tactical multiplayer FPS crafted by BlackMill Games, known for their critically acclaimed authentic WW1 wargames such as Verdun and Tannenberg. Immerse yourself in faithful recreations of historical battles with intense 48-player matches, testing your tactical skills and mastery of Alpine warfare.

Decide your path to victory: whether you’re leading the offensive with grenades or using mountain trails to flank enemy positions, you have options. Dive into combat or take a supporting role cutting barbed wire and crewing heavy machine guns and mortars. Thanks to a unique flare gun system, mark targets for artillery strikes or biplane flybys, before charging in to finish the job at close quarters with bayonets or trench clubs.

Choose from six distinct classes and build your loadout from a selection of 50+ iconic WW1 weapons, along with historically accurate equipment and perks specific to each class. Play as a Marksman to pick off soldiers from afar, storm enemy lines with the Assault class, issue tactical orders as an Officer, and much more.

After choosing a class, make it your own by picking from a large variety of role-appropriate uniforms, accessories and headgear. As a finishing touch, you can even pick your mustache from several famous wartime styles!

From hillside fortresses to mountain trenches and city streets, fight through varied Alpine landscapes inspired by historical battles. Learn the lay of the land to maintain cover and surprise your enemies - or go a step further to shape a dynamic battlefield by placing sandbags, barbed wire and ammo crates. Trench periscopes and sniper shields offer even more tactical options, but beware of poisonous gas attacks and artillery barrages!

Taking inspiration from the years-long struggle for control of the Alps during World War One, Isonzo brings the authenticity of the conflict to all players. Everything is recreated based on research and field trips, from sound effects, weapons and uniforms down to the houses, vineyards and trenches you’ll be fighting over. Choose your side and immerse yourself in History!
