Call of Christmas



Ho, ho, ho, Generals!

Pack your warmest clothes and fastest sleds for our ‘Call of Christmas’ event! In this exclusively available event map remnants of the ‘Third Reich’ have kidnapped the world’s biggest industrialist (Codename: Santa) in Antarctica to capitalize on his skills.

Your mission: Conquer and hold two of three Control Points for four ingame days to free Santa and win all his riches (50,000 Gold!).

To spice things up, we removed a lot of AI provinces and made all player countries completely conquerable. Additionally, most resources on the map are now concentrated in several resource hotspots.

During this event Supply Drops spawn much more frequently on the map, giving you an additional chance to collect resources or a valuable blueprint for elite level units as a Christmas gift for yourself this year.

What will be your strategy? Will you secure the Control Points for an early victory, or will you fight over the valuable resource hotspots and supply drops to sustain your army? Decide wisely and strike fast to save Christmas!

Event details:

  • Player count: 50
  • 2x speed
  • All provinces conquerable
  • No coalitions
  • Increased Supply Drop spawn
    • Supply drops can spawn within the first hour of a game
    • Supply drops can be collected until 6 real time hours after they spawned

  • Winner receives 50,000 Gold
  • Random country selection
  • Starts immediately

Release Notes



Attention, General!

With our last update for 2021 we implement a long list of bug fixes to Call of War!

The lasso tool, which didn't work in some areas on some maps, is working as intended again. Planes are no longer taking a detour around the world, but take the shortest route available again. Ranged units like Artillery also do not temporarily stop moving when attacked by enemy ranged units when on their way to a location. These are just some examples of today’s bug fixes. The list goes on and on.

Apart from taking care of bugs we also re-implemented markers in the center of patrol circles of planes, added confirmation popups for important orders in the game, and renamed High Command to Premium Account.

As usual you find a full list of all changes in the forums and on our Discord server. This is only the last update of 2021. We will continue our efforts and bring new content and features to Call of War in 2022!
