Release Notes



Attention, General!

Booster Cards have been rebalanced! To make Booster Cards more intuitive to use, we have unified the values provided across Card sizes. For example, a Small Booster Card will now always deduct 15 minutes, regardless of whether it’s used to speed up construction, production or research. Similarly, using a Medium Resource Booster will now always give you 1500 units of that resource, regardless of type.
As this means that some of your existing Cards were converted, we made sure that you don't lose any value! All your Cards have been converted to the bigger size available, meaning that you won’t miss out on valuable resources when you need them the most!

Further, we made some much needed quality of life improvements. Whether you are engaged in high stakes diplomacy, or are simply requesting some much needed resources from your allies, the newly reworked trade interface will keep you in the loop. This way, you won’t be on the wrong end of a misguided trade deal!
And to prevent mistakes even more fatal than a diplomatic mishap, we have added an indicator showing you the impact and fallout radius of nuclear weapons when selecting their target.

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.

Best of luck General!
