Release Notes - 2022-11-22



Attention, Generals!

Today we’ve added two new terrain textures! In the north you will find a cold, icy tundra, while arid zones are dominated by dry, unforgiving deserts! Tundra and desert provinces are just a visual variation of the Plains terrain and grant the same terrain bonuses, making tanks and Motorized Infantry the weapon of choice to dominate the battlefield with.
We also took this chance to improve the look and feel of plains and forest textures. Not only are they now more beautiful, they are also more easily distinguishable from one another. This will allow a savvy commander to quickly analyze and exploit the battlefield’s environments.

Good news for diplomats: we’ve fixed the bug that caused the chat to not scroll to the newest message anymore when exchanging diplomatic messages. It will now automatically scroll to the newest available message.
Further, we’ve improved access to the general chat on mobile devices. While in the main menu, you can now open the chat from the “More” menu in the bottom taskbar.

We wish you success on the battlefield!

Release Notes - 2022-11-08



Attention, General!

We’ve updated the rewards for completing the research steps of the tutorial. Players will now have the difficult choice between a Tank Destroyer and a Medium Tank. This way new players get more options in how they approach their first game.

We also fixed a bug that caused newly produced planes to turn into convoys when sent to an aircraft carrier produced in the same province. As this caused traffic congestion on highways, planes will take to the skies again when given carrier duties.
Also carrier related, we fixed an issue that caused planes to disappear when splitting a carrier stack. Planes will now be evenly distributed among the split carriers.
Additionally, we fixed an issue on mobile devices that made it impossible to close the reward popup window when finishing adviser tasks.

Release Notes - 2022-10-25



Attention, General!

A shiny new update has been deployed, featuring some menu improvements and bug fixes. Let’s get right into it!

It is now easier to join event and scenario maps with the new “Find Games” button that was added today. It’s located at the bottom of the event’s information window and takes you directly to the games list.
We’ve also made improvements to the Alliance vs Alliance challenge menu. A new, clean look is combined with more available information about the challenge.

The missing toggle button to switch between the default and the historical unit pictures has been located and is back in service.
We also fixed an issue in the missing requirements window on mobile. It will now correctly display as red when research can’t be started because of game day limits.

For a closer look at all the changes please check out the detailed Release Notes and share your feedback with us on the Forums and our Discord Server.
We wish you the best of luck in all your battles!
