Release Notes



Continuing on in our efforts to finetune War Bonds, we are making more impactful changes rto Call of War’s latest resource. On all newly created maps, players will now start with 5,000 War Bonds instead of the previous 10,000. This limits the amount of havoc that War Bonds can cause in the very beginning of the game, letting players settle in better when joining a map.
Additionally, users with Premium Account will now enjoy a 20% increase to the production rate of their War Bonds. This means that the hourly production rate will go from 1,250 to 1,500, giving Premium users one additional special action per gameday.

We also fixed a bug that caused units stationed in allied territory to automatically attack instead of defending when engaged by enemies. Now, these units will correctly use their defensive combat stats.

Finally, we are in the process of implementing a moderation tool that automatically checks the newspaper for prohibited content. Please refer to our FAQ section on Helpshift if you have any questions about this change.


For a complete overview of this update, please check out the detailed Release Notes and share your feedback with us on the Forums and our Discord Server.
