This historical game takes place across the lakes, forests, and snowy plains of the Eastern Front - it was inspired by the Battle of Tannenberg in 1914 where the Russian Second Army was dealt a heavy blow by the Germans. Tannenberg offers a range of game modes - including the exciting new mode reflecting the different nature of war on the Eastern Front - and a wealth of historical detail: realistic WW1 weaponry, authentic uniforms, horrendous gore, and maps based on real battlefields, this time in the forests, plains and mountains along the border between the Russian Empire and the Central Powers.
Tannenberg key features include:
- Realistic World War 1 gameplay
- Tactical squad-based FPS
- Warfare on the Eastern Front
- Majestic backdrops and map detail
- Variety of game modes for player counts of up to 64
It’s all-out war on the Eastern Front! From artillery barrages and poison gas to the deadly machinegun and humble rifle, there are many weapons to master. The battlefield is a dangerous place, and a little thought will help you stay alive – lead your shots, keep your eyes open, and be ready to engage in ferocious close combat at any moment.
Authentic Eastern Front Warfare
The development team is aiming to recreate the atmosphere of the Eastern Front with the same level of accuracy as in Verdun. Uniforms have been recreated to the tiniest detail, the weapons are modeled to exact references and the maps use realistic props and terrain layouts.

What do you mean youve already had way too many recaps this year?
Hello everyone!
We hope youve had a great 2025! For the WW1 Game Series, it was a very special year. Weve been very busy behind the scenes preparing for the release of Gallipoli in 2026, but lets take a moment to look back on everything that happened in 2025.\n
The Moschin Expansion & free DLC Upgrade
Isonzo got its final expansion: Moschin! This map is the only night map in Isonzo, set in the burning woods of the Grappa massif. As the Austro-Hungarians attempted to circumvent the Piave river in June 1918, they commenced a heavy bombardment on the Italian defenses. However, the Italians knew what they were up to, and counterattacked at just the right time.
Along with the map came the Beretta M1918, an Italian semi-automatic carbine with an incredible fire rate and capacity, perfect for aggressive manoeuvers. For the Germans looking for a grenade with a bit more bang for your buck, the M1917 Geballte Ladung 6x is all you need!\n

The Avanti Savoia Units DLC that came for free with Isonzo for those who got the game in the first week of launch had a huge uplift. Its now a fully- fletched DLC with over 50 rare and late-war items. The best part: if you already had the original DLC, this upgrade is completely free. Thank you for your continued support!

The Big Gallipoli Announcement
Of course, the highlight of the year is the announcement of Gallipoli! This fourth game is taking the series to the Ottoman Fronts, where the Entente, notably including Anzac and Indian forces, open up the attack on the Ottoman Empire.
For Gallipoli, we put a big focus on the look & feel of the game, taking the immersion and simulation aspects to the next level. Its set to release in 2026, so be sure to add it to your wishlist if you havent already!
Anniversary Trailer
We celebrated the 12 Year Anniversary of the WW1 Game Series with a huge sale and a compilation trailer for a trip down memory lane!
More Gallipoli Info
In the months following the announcement, we started sharing more info about Gallipoli.
Expedition Game Mode
We first took a look at the game mode of Gallipoli: Expedition. This mode captures combat as it was like on the Ottoman Fronts, revolving around momentum and all-out assaults. Objectives are now also randomized to a degree, so work with your squad to make decisions on the go!\n
For the full explanation of the Expedition game mode, check out the blog!

Ctesiphon & Anzac Cove
Next, we looked at two of the maps coming to Gallipoli!
Ctesiphon is set on the Mesopotamian front, where British and Indian forces landed to secure Basra and the oil fields further inland. This is an arid region with vegetation along the banks of the river Tigris, but its prone to sandstorms. You may want to take shelter by the Arch of Ctesiphon!

Anzac Cove is known for the landings by the British and Anzac forces on the shores of Gallipoli. Their goal was to capture Constantinople and knock the Ottoman Empire out of the war, but they faced much stronger resistance from the Ottomans than expected. The terrain consists of ridged hills and vegetation that can provide both some cover and make you cross wide-open areas.

First Gameplay Details
Then, we shared some of the work-in-progress gameplay changes planned for Gallipoli. From pacing to animations, damage and ballistics, we showed a lot of the improvements coming to the game. Take a look for yourself!

Changing the Gallipoli Subtitle
Now with Gallipoli coming together, weve taken a close look at the scope of the game. To better reflect the fronts outside of the Middle East that saw Ottoman action, like the Gallipoli campaign itself, weve decided to change the subtitle of Gallipoli from Middle Eastern Front to Ottoman Fronts.
In the upcoming months, well reveal more maps coming to Gallipoli at launch. Stay tuned!
