About the Game

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!


Enlist for more First World War action with the other standalone titles in the WW1 Game Series: Gallipoli, Tannenberg and Verdun. Engage in expeditionary warfare on the Middle Eastern Front with Gallipoli, maneuver for control of key sectors in Tannenberg on the Eastern Front OR Dive into the trenches along the Western Front in Verdun. Choose from a range of squads from across the war, as they fight for control of the ever-changing frontlines.

AVANTI SAVOIA!
Under the cover of darkness, the Austro-Hungarians push towards the northern Italian defenses. With their surprise attack plans foiled, a moonlit battle of fire and chaos commences: Moschin.
This update includes the Moschin map, 2 new weapons and the reinforced Avanti Savoia Units Pack DLC, upgraded for FREE as a thank you for your continued support since launch!
New Map: Moschin
The Austro-Hungarian 11th army pushes south across the Grappa massif, aiming to break through the Italian defenses and attack the deployment along the Piave river from behind. They planned an attack at night, preceded by a heavy artillery bombardment to weaken the Italians.
Firing commenced, but while the infantry moved into position, the Italians fired back with devastating results after having learned of the Austrians’ plans. The now weakened advancing forces reach the Italian defenses and a fiery battle is fought at Col Moschin.

Moschin (pronounced: [moˈskin]) is a map of two lighting extremes that will have you either sneak through the trees under the cover of darkness or parkour around the blazing heat. It features three objectives, with the last being a cluster of trenches and gun nests that’s sure to allow for some chaotic last stands!

The German Empire got themselves another new addition to their kit! The standard M1917 Stielhandgranate didn’t always have enough oomph, but the solution was right around the corner: just strap on more explosives! With six more explosives strapped onto the grenade, the M1917 Geballte Ladung 6x sports a longer fuse time and shorter throw range than the Stielhandgranate, but extended lethal and non-lethal blast radii. You can get it for Engineers and Assault units!
{STEAM_CLAN_IMAGE}/40153298/c3a5b7d70b674d07c40fb006b8197b76102a115b.png
Now the Italians get our best kept secret. A weapon no one saw coming and we definitely didn’t leak multiple times already. *Ahem* As one half of the Villar Perosa developed into a semi-automatic carbine, the Moschetto Automatico Revelli-Beretta (or Beretta M1918 for short and MAB-18 for shorter) only has pistol-like stopping power, but makes up for it with high fire rate and capacity, as well as the range and accuracy closer to that of a carbine. Even though the magazine tends to block your view, the Beretta M1918 proved to be very powerful and had to be limited to two users only, like the Artillery Luger. Available for Assault!

Reinforced Avanti Savoia Units – Free Upgrade!
This expansion also brings a new(ish) cosmetic DLC! Featuring a wide array of late-war uniforms and rare headwear items, the Avanti Savoia Units Pack DLC is sure to add some pearls to your extensive wardrobe.
Some of the more visually distinct items include sapper outfits for both factions, fezzes, prototype helmet armor and helmets with camouflage paint, a significant historical contribution to WW1 and wars since.

Looking forward
As many of you have noted, the release of the Moschin Expansion marks the end of the roadmap for Isonzo! It’s been an amazing journey of 8 free expansions in a little under 3 years bringing new weapons, gear and maps that explore many corners of the Italian front of WW1.
We’ve had a lot of questions about what’s next after this roadmap. To answer those questions: there will be more, just not another roadmap. The Moschin Expansion is the final expansion planned for Isonzo. It’s not the end of the road for the game though, as we still have some improvements & updates in mind and Ascent will reappear soon!
{STEAM_CLAN_IMAGE}/40153298/5c5cad0aa04ec3cdb0003ad72bf5d568f53ce293.png
Again, a big thank you to all of you for the continued support over the years, Isonzo and the entire series. We hope you enjoy the new update and the Avanti Savoia Units Pack DLC, filled to the brim with highly requested items and our finest quality work yet. See you around for the blog posts yet to come, and we’ll have a big announcement coming this summer.

New map: Adamello
The Italians launched a large-scale assault on the Presena Glacier held by Austro-Hungarian. Attacking from multiple angles, the Italians swiftly captured the forward positions of Zigolon and Marocarro. Cima Presena proved to be a bit more difficult as the Austro-Hungarian defenses were solid. That’s where you come in!
{STEAM_CLAN_IMAGE}/40153298/a542b639bf981d72ce95e714e181b9551def506b.jpg
Now, as you might be able to imagine, the alpine weather at an altitude of 3000 meters is a force to be reckoned with. This battle was extremely cold and snow storms were frequent. During winter, the weather got so bad and the snow so thick that fighting simply became impossible. The battle may have been between two armies, but there’s truly no foe like the weather: nessun nemico come il tempo.
{STEAM_CLAN_IMAGE}/40153298/61aa5d6194abdc31fd6c03e237b8978d1ac15482.jpg
In Isonzo, Adamello features three distinct lanes, two of which have you plough through the snowy trenches to get to where you need to be. The third lane has you fight on the other side of the ridge, where you really need to watch your step if you value your life.
For the finale, all three lanes merge into a large open area with very little cover. The Austro-Hungarians are defending the peak and the Italians will need to climb to it!

New weapons
The Adamello Expansion includes two new weapons, an impact grenade for the Italians and a “rifle” for the… Germans? Surprise!
Yes, the German Empire gets its hands on the Artillery Luger this update. It’s a variant of the Luger P08 frequently used by the Stoßtruppen, filling the role of a lightweight rifle or carbine. It features an extended barrel, shoulder stock with a holster and a Trommelmagazin with a whopping 32 round capacity. Regardless of these modifications however, it’s still a pistol: its low power makes it not as reliable as a rifle and damage drops off quickly over longer ranges. You can find the Artillery Luger among the main weapons of the Engineer and Assault classes!
The Italians get the Petardo Offensivo P.O., a late-war redesign of a French grenade. It wasn't that powerful, but very noisy, which made it ideal for provoking fear in the enemy. In Isonzo, the P.O. is a relatively low-powered grenade that explodes the moment it hits something, be it the ground, an enemy or an ally. If you do hit an ally with this impact grenade, they won’t be damaged. If you’re in the blast radius as well however, you may be less safe! It’s available to the Rifleman, Engineer and Assault classes.
{STEAM_CLAN_IMAGE}/40153298/d41e4e010160eb9f5b71bf408de3df10aade0bf2.png
Ascent: Round 2
Ascent makes its return and we know you’re excited to get back to climbing! This limited-time game mode has the Italians grapple up the rocky cliffside of Marmolada using ice picks and rope to get to the objective at the top. The Austro-Hungarians are defending the summit and will need to defeat the Italians with the limited ammo they have – though when in a pinch, a rock aided by gravity will leave a lasting impact as well.
For more information about Ascent, be sure to check out the original announcement:
https://store.steampowered.com/news/app/1556790/view/4187858160677938414
The Ascent event is available on all platforms until November 26th, 10 AM CET. Be sure to give it a go, as there’s an achievement up for grabs!
