I'm sure many are familiar with the in-game messenging/voice chat/etc client Xfire. It has support for many SubSims, including Silent Hunter 3, Silent Hunter 4, and Dangerous Waters.
But not 'Shells of Fury'. Yet! Generally, Xfire support is added to newer games when the devs can see that there is general interest for that.
So, to that end, if you use Xfire, and would like the ability to chat in 'Shells of Fury', track time played, etc - post
over in the Xfire forums in my thread, here.
Yes, it's a long shot, as 'Shells of Fury' doesn't have any multiplayer support itself - but Xfire can chat across games just fine (so when you are playing this game on your own, you can still chat with other friends online playing Sh3/DW/Battlefield/etc), so I think it's still worth petitioning for!
