Release Notes - 2023-06-27



Attention, General!

Following up on the changes from the end of May, we are making further changes to the game’s balance. Thank you to all our players for the great feedback! It made us rethink our buffs to Railroad Guns. It also sparked follow-up changes to buff the Allied and Comintern doctrines.
We reverted the buffs to Railroad gun production. Now a Secret Lab at level 4 is again required to ensure efficient production.
Further, we increased the damage of Commandos, Anti-Tanks as well as Tactical and Attack Bombers. We want to strengthen units that profit from Allied and Comintern doctrine buffs to make those doctrines more competitive with their Pan-Asian and Axis counterparts.
We also buffed the movement speed of SP Anti-Air. That way motorized offensives no longer have to compromise on either speed or anti-air.

And with that, we come to the bug fixes for this week. Enjoyers of sub-surface warfare rejoice! Submarines are no longer visible even when undetected. We also fixed a bug that caused stealth units to become visible when stacked with non-stealth units.

For a closer look at the changes please check out the detailed Release Notes and share your feedback with us on the Forums and on our Discord Server.

Best of luck General!

Operations - New Feature



"Amateurs talk about tactics, but professionals study logistics."
- General Robert H. Barrow

We are very excited to present Call of War's latest feature today - Operations!

The Operations feature provides you with long-term tasks you fulfill while playing the game. We planned Operations to include a variety of different tasks that allow us to provide you with exciting challenges. Starting with simple tasks like buying something in the shop, to more complex challenges that encourage you to change your usual play style.

You can open Operations via the new icon that is displayed on the right side of your screen when you are in a game round. Clicking or tapping on it will open the Operations screen. Here you find all available Operations and an overview of your current progress with each Operation.

Operations have several Milestones that you unlock one after the other. To complete an Operation and its tasks, you have only a few weeks. Once you reach a Milestone you can claim the linked reward in the Operations section too. To progress towards a goal, you simply tackle the task presented in the Operations. You don't need to do anything else. The action will automatically be registered and accounted for any currently available Operation. Check your available Operations and adjust your gameplay accordingly to swiftly complete each Operation's goals.

Today starts the very first Operation of this brand-new feature in Call of War! We are planning on adding new tasks and goals to it. We have many great ideas for this exciting new feature and would love to hear your ideas for tasks on our Discord server and on the forums.

Please note that this new feature is currently only available on mobile.
