A New Era Begins - Uniting Our Games & Studios



Big changes are on the horizon, and we’re excited to share them with you first! After years of collaboration, Bytro and Dorado are officially becoming one unified company. This marks a new era—a fresh start with a new look, new aspirations, and bold ideas for the future.

We are aligning our strengths, refining our goals, and setting the stage for even greater strategy gaming experiences. This transformation is about more than just a name; it’s about reinforcing our commitment to our players and ensuring that our games continue to evolve while staying true to their roots.


But that’s just the beginning.

A Unified Franchise: Welcome to the Supremacy Era

With our studios coming together, we are also aligning our games under one unified Supremacy franchise. Supremacy 1914, Call of War, and Conflict of Nations will now carry the Supremacy name—creating a recognizable brand that strengthens all of our strategy games while keeping each title’s unique identity intact.

Here’s what this means for you:

Same core gameplay & mechanics – No fundamental changes to how your favorite games play.
No progress loss – Everything you’ve earned stays with you.
More content & improvements – A stronger foundation for future updates and community support.

Rebranding: A New Look, Same Great Games

As part of this evolution, the games will receive a branding update:

  • Supremacy 1914 – Stays the same!
  • Call of War – Will transition to Supremacy: Call of War 1942.
  • Conflict of Nations – Will become Supremacy: World War 3.

This helps players instantly recognize the connections between our games while preserving their distinct gameplay and settings. Think of it like other popular game franchises—different titles, but all part of the same legendary franchise.

What’s Next?

New Studio Name – A single name to represent our combined strength.
Unified Login – Work is underway to streamline access across all games.
Shared Community – We’ll transition to a single Supremacy Discord server for a stronger, more connected player base.
More Games in the Future? – While nothing is official yet, this new structure paves the way for future expansions.

Your Role in This Evolution

We know change can bring questions, and we’re here to answer them. This is a collaborative journey, and your feedback is key to making this transition smooth. Join the discussion, share your thoughts, and let’s move forward together.

More updates will follow soon—stay tuned!

Call of War 10th Anniversary! - Celebrate a Decade of Strategy!



Attention, Generals!

Whether you're a seasoned strategist or a new recruit, your participation has been part of the journey that has shaped this legendary game.

To celebrate this remarkable achievement, we're throwing an epic event in honor of all the players who’ve made Call of War what it is today!

Battle Front Europe Event:

The year is 1939, and Europe stands on the brink of war. Tensions have reached a boiling point, alliances are shifting, and the fate of the continent is hanging by a thread. The time for diplomacy is running out—soon, the clash of ideologies and rising military powers will decide the future of Europe.

In this Battle Front Europe event, 24 players will command nations across Europe, each with their own ambitions and strategies. The winner will be the one who claims the most victory points, either through ruthless solo conquest or through strategic alliances.

With 2x speed and a map that ends in just 14 days, the stakes have never been higher. Every single rural province grants victory points, while urban provinces reward 10. Outmaneuver your opponents before they can strike first. Every second counts—will you act swiftly or be left behind?

Event Details:
  • Player count: 24
  • Speed: 2x
  • Starts immediately
  • Free country selection
  • Max members in a coalition: 2
  • Map duration: 14 days
  • Solo victory: 700 victory points
  • Team victory: 1200 victory points
  • Victory points per province: 1
  • Victory points for urban provinces: 10
  • No AI peace period

With tensions mounting and alliances shifting, who will rise to dominate Europe, and who will be left in the dust of history? The battle for Europe begins now—seize your moment!

And if that’s not enough, we’ve got your favorite event maps running from May 1st!

Enjoy fan-favorites like:

  • Swift Strike
  • Team Up
  • 4x Free For All
  • 4x All Countries All In

...and many more throughout the week!

Thank you for being part of the journey.

Here’s to 10 years of strategy, and many more to come.

Enjoy the 10-Year Anniversary—and thanks for playing Call of War!

Free For All - Speed Event




Generals!

In this week's event you'll only be able to rely on your own wits and skills to emerge victorious. Doing so in the regular Free For All event is already quite a challenging task, but doing so at increased game speed is truly a feat achievable by only the most competent of strategists.

In a 100p map with the ‘anonymous round’ feature enabled and no coalitions, you will be pitted against 99 other players in a struggle for survival. The event maps will start immediately after their creation with random country selection enabled and will run at 4x speed. Should no single competitor conquer the required amount of victory points before the time is up, the player with the highest total of victory points is declared the winner, earning not only a generous victory reward, but also the right to declare themselves to be amongst the best of the best.

Good luck, Generals!
