About Isonzo

From the makers of Verdun and Tannenberg
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.

Offensive Game Mode

The new Offensive game mode puts you right in the middle of key historical offensives on the Italian Front. Lead the charge across stunning Italian landscapes as you choose your path to victory - cut paths through barbed wire, flank your enemies by following mountain trails, or man a mortar to blast a way through. Shape a dynamic battlefield by laying sandbags and wire, placing ammo crates, deploying trench periscopes or sniper shields, and more.

Authentic WW1 Combat

Call 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.

Class System

Choose 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.
Being 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!

We're in a milsim boom and Isonzo's thrilling, if limiting battlefields fit nicely into it.
by Luke Winkie
7 / 10
Isonzo is a well-made shooter that welcomes all comers to its gorgeous, mountainous World War I multiplayer battlefields, though a lot of that approachability and familiarity comes at the cost of period authenticity and distinctive gameplay.

Isonzo changes the formula of the WW1 game series -- and it's all for the better.
