Dear NF2 Captains,
We are proud to announce that Navy Field 2 will be officially available for all Steam users very soon. New Steam users will join us on the existing server, so please prepare to welcome them.
While we took all measures to ensure that the Steam launch is seamless, current standalone NF2 accounts will not be able to login through the Steam version and vice versa without modification. In order to get around this, we have created an optional method to convert your current standalone account into a Steam compatible version if you find it to be more convenient for you. Please Help. Thanks !
I didn't find the right solution from the internet.
