Hello everyone! We just released patch 1.11.13 for "Barbarossa" on Steam and Microsoft Store. The new checksum is d173. This update introduces the possibility to play multiplayer games across stores (such as Steam and Microsoft Store) using the Nakama network solution already in use in other PDS titles. See the FAQ below for more details. Saves made with 1.11.12 are expected to be fully compatible with 1.11.13 and you can continue your previous game. If you discover any bugs in patch 1.11.13, first check the known issues list, and if necessary please report them in the bug report forum as usual. Nakama Crossplay FAQ What is Nakama Crossplay? Nakama is a network solution that is independent of the store you bought the game on (be it Steam or Microsoft Store) and allows you to play with your friends regardless of where they have the game. Does it replace the current network layer? Nakama does replace the current solution (PDX MP) on Microsoft Store, but on Steam it is an optional alternative you have to select when launching the game. By default the game will behave exactly like it did in the previous release on Steam. How does Nakama compare to Steam MP? First and foremost, Nakama allows you to play across game stores, something our current implementation of Steam MP is unable to do. Secondly, it does not rely on direct connection, meaning it makes it impossible for clients to know the real IP address of the host (and vice versa). This comes at the cost of some extra latency, so depending on where the players are located in given MP session you may experience higher ping than with Steam MP. How do I enable Nakama MP? Nakama is always enabled on Microsoft Store. On Steam, you will get prompted to select if you want to start with Steam MP or Nakama MP when launching the game. Starting with the first two options will start the game with Steam MP as usual.
Once in the game, you can tell which version was used by looking at the bottom of the main menu. The letter (S) or (N) after the checksum tells you whether you are using (S)team or (N)akama.

Why does the game ask for a Paradox Account to play with Nakama? The matchmaking service needs to be able to identify players across game stores, so we cannot effectively use your Steam or Microsoft Store ID. Instead, we rely on your Paradox Account user to be able to host, view and join other players games.
