🗡 Fuf! 10 years, huh? A long time ago, we started this journey — packed all our swords and shields, built our Chaikas and ran into the darkness of war. Since then, we haven’t had a moment of peace, but we found peace in these battles. Win after win, run after run, push after push — we never stopped, always moved forward. And we did it. We came here, to this moment — with tons of victories behind, with hundreds of victories ahead. This is the 10th anniversary of Cossacks 3, friends. We want to thank you from the bottom of our hearts for being with us all these years. We wouldn't have made it this far without you. Your GSC Game World team.

🗡 Уф! 10 років, так? Дуже давно ми розпочали цю подорож — спакували всі наші мечі та щити, побудували наші «Чайки» й кинулися в темряву війни. Відтоді у нас не було ані хвилини спокою, але ми знайшли його саме у цих битвах. Перемога за перемогою, пробіг за пробігом, наступ за наступом — ми ніколи не зупинялися, завжди рухалися вперед. І ми це зробили. Ми дійшли до цього моменту — маючи за спиною безліч перемог і сотні попереду. Друзі, сьогодні виповнюється 10 років від виходу гри «Козаки 3». Ми хочемо від щирого серця подякувати вам за те, що ви були з нами всі ці роки. Без вас ми б не дійшли так далеко. Ваша команда GSC Game World.

🇺🇦 Today Ukraine celebrates the 35th anniversary of Independence. 35 years of brave and often hard decisions. Years full of exciting moments and tragic events that didn't stop us but inspired us to keep trying. 35 years of establishment and fighting to form the national identity that all Ukrainians carry inside their hearts. The road had its fair share of challenges that nobody would go through willingly. But we will push through. With love for our families, respect for our homeland, and a thirst for freedom that no one can take away from us. Happy Independence Day, Ukraine. We love you so much. GSC Game World Team

18 years ago, the Swamps whispered beneath a Clear Sky. Years pass. Factions fade. But the Zone remembers — and some old voices of Clear Sky can still be heard, if you know where to listen. Perhaps one of them is already closer than you think. Happy birthday, S.T.A.L.K.E.R.: Clear Sky.

28 awards. 1 Grand Prix. One important message. Our mine safety campaign, created in collaboration with the State Emergency Service of Ukraine, UNICEF Ukraine, and Rockets. Growth R&D, became the most awarded creative project of 2026 in Ukraine at Ukrainian Creative Stories — a unique platform that brings together the country’s leading national and international advertising festivals. The initiative’s visual concept, based on S.T.A.L.K.E.R. 2: Heart of Chornobyl, used game design to raise awareness among teenagers about mine safety in Ukraine. We are incredibly grateful to everyone for this initiative — yet another opportunity to remind people of the important realities of today.

40 years since the Chornobyl tragedy. We thank all the colleagues and partners who helped bring this initiative to life — but above all, we thank the people whom Chornobyl has touched directly. Even after 40 years, the Chornobyl disaster remains an example of heroism, dedication, and self-sacrifice. And you found the strength to relive those events once more and tell your stories again. The Chornobyl disaster. Let us remember. 1986 — 2026.

The stories of Chornobyl live among us. In hundreds of thousands of families, in their memories, in the paintings on the walls, and in the memorials of our cities. They live in liquidation awards, legends, and documentaries, in the silence across the streets of Prypiat. And in the fates forever changed by the tragedy of 1986. Almost 40 years later, these stories are still here; we know a lot of them, but even more remain unheard. Together with the Ukrainian National Museum Chornobyl and the State Agency of Ukraine on Exclusion Zone Management, we are launching the Chornobyl Stories social project — a space for those who have something to tell. The stories of liquidators and families leaving their homes. Stories of those who helped others. Stories of your parents, grandfathers, and grandmothers. Stories of people who are no longer with us but whom you still remember. Tell your story. From today until the end of March 2026, you can share your memories, add photos, or upload materials you consider important on a dedicated website: chornobylstories.info In April, the month of the 40th anniversary of the Chornobyl tragedy, we will collect these stories and share them with the world. This idea is not just about the stories from the past; it is about Chornobyl and what it really is.

Історії Чорнобиля живуть поміж нас. У сотнях тисяч сімей — у спогадах; у назвах вулиць наших міст і картинах на стінах; у відзнаках за участь у ліквідації; у легендах та документальних серіалах. У мовчанні вулиць Прип’яті. У долях, які змінила трагедія 1986 року. Майже 40 років потому ці історії нікуди не зникли. Багато з них ми знаємо. Але ще більше — так і залишилися непочутими. Разом із Національним музеєм «Чорнобиль» та Державним агентством України з управління Зоною відчуження ми запускаємо соціальний проєкт «Історії Чорнобиля» — простір для тих, кому є що розповісти. Це історії ліквідаторів і переселених сімей. Історії тих, хто допомагав іншим. Історії ваших батьків, дідусів і бабусь. Історії людей, яких уже немає, але яких ви памʼятаєте. Розкажіть вашу історію. Від сьогодні й до кінця березня 2026 року на спеціальній сторінці ви можете поділитися спогадами, додати фото чи матеріали, які вважаєте важливими: chornobylstories.info У квітні — в місяць 40-річчя Чорнобильської трагедії — ми зберемо ці історії та поділимося ними зі світом. Ця ініціатива — не просто про історії з минулого. Це те, чим і є Чорнобиль.
