Isonzo PC Steam CD Key
Description
Ferocious Alpine warfare will test your tactical skills in this authentic WW1 FPS. The battle among the scenic peaks, rugged valleys, and idyllic towns of northern Italy. The Great War on the Italian Front is brought to life and elevated to unexpected heights!Take part in historical offensives from the Sixth Battle of the Isonzo to the Strafexpedition. Reflecting the course of the actual battles, as the attackers advance the fighting will shift through vastly different landscapes within a single offensive: from hillside fortresses to mountain trenches and fierce urban combat on city streets. Everything is recreated based on research and field trips, from sound effects and uniforms down to the houses, vineyards, and trenches you’ll be fighting over. Stunning Italian LandscapesCall in support with a unique historically accurate flare system: flare guns can mark targets for artillery or biplane flybys, or different colored flares can be used to guide your team. Once the big guns have softened up the enemy, finish the job at close quarters with an Arditi dagger or mountaineer’s pickaxe. Man-heavy machine guns, mortars, and even mountain guns for more direct fire support. Iconic WWI WeaponryChoose from six classes based on historical combat roles and build your loadout from a selection of weapons, equipment, and perks linked to that class, giving flexibility and variety while staying grounded in what real soldiers might have carried. You’ll be operating wire cutters, bandaging yourself and wounded teammates, and blowing the whistle to start an assault. One shot can kill and even lighter injuries can lead to quickly bleeding out. Dynamic BattlefieldBeing an effective soldier in Isonzo is not just about being a good marksman. Mastering the terrain is also key - the mountain can be a friend or foe. Learn how to navigate well to maintain cover and surprise your enemies or support your allies. Finally… watch out for the dreaded poison gas. You’ve never experienced WW1 action quite like this! Features: Mountain warfare: Assaulting mountain fortifications, battling through ruined towns, and fording rivers are just a few of the challenges you’ll face as you fight your way through numerous enemy positions Tactical multiplayer FPS: Choose your role and loadout carefully to survive this high-altitude combat - play a sniper to pick off the enemy engineers before they can cut your wire, use rifle grenades to clear enemy machine guns, and much more World War One Gameplay: Historical Offensive game mode based on real battles and focused on the unique challenges of Alpine warfare. Fight with 30+ WW1 weapons, poisonous gas attacks, and intense artillery barrages Build for victory: Place your own wire, sandbags, trench periscopes, and more! Whether you’re digging in or on the attack, shaping the battlefield to your advantage will be key to victory Faces of war: Make every class your own by picking from a variety of historically class-appropriate uniforms, accessories, and headgear. As a finishing touch, you can even pick your mustache from several famous period-accurate styles! Authentic WW1 atmosphere: Accuracy in everything from maps and weaponry to music and the uniforms – fight for the Kingdom of Italy or the Austro-Hungarian Dual Monarchy
