CoW Community for Earthquake Victims - Bytro helps



Attention, Generals!

Beginning of February, the south of Turkey and north of Syria were hit by a major earthquake that affected millions of people and killed tens of thousands.
The Turkish players of our games and our Turkish volunteers were looking for ways to support their fellow players who are currently affected by the aftermath of this devastating earthquake.

To see players coming together to help other members of the community is wonderful, and Bytro would like to join this effort. We have therefore decided to donate 2,000.00 EUR to DRK (German Red Cross) on behalf of our players.

On top of this immediate support, we will donate all earnings made in February, March, and April 2023 from the Call of War, Supremacy 1914 and Iron Order Merch Store to DRK (German Red Cross).

If you wish to join this effort and would like to donate directly, you can do so on:

drk.de (German Red Cross)
ifrc.org (International Federation of Red Cross and Red Crescent)
sams-usa.net (Syrian American Medical Society)
emiratesrc.ae (UAE Red Crescent)

We want to do justice to our amazing community initiative and thank them for their magnanimity.

[Speed] World at War - New Map & Release Notes



Attention General!

We have exciting news today! The popular 'World at War' map is now permanently available in a new version for you! The new '[Speed] World at War' map comes with a speed factor of 4x and allows for up to 56 in-game days of intense fights between up to 100 players!
Play in a coalition with up to five members or aim for the Solo Victory and dominate the world all by yourself.
Join the new [Speed] World at War now!

Parallel to the new [Speed] World at War map, several improvements and bug fixes were implemented with today's update as well. Game panels now inform if a map has a higher speed factor and the stop button also cancels Convert, and Upgrade orders!

Furthermore, the inventory system, that is currently available to a limited number of players on mobile devices, is now also available to these players when playing the game on desktop.

The list of bugs that were removed with this update is long in general. Armies that don't trigger war when moved to a neutral province center, rockets that return mid-flight when an airfield was destroyed or the chat becoming transparent every time it gets updated are just a very few highlights of the full list.

For a complete overview of all changes, please grab something to drink and check our detailed list of updates and share your feedback with us on the forums and our Discord server.

Best of luck General,
Your Bytro Team
