Multiplayer
 

I'd like to try the MP mode, but there never seems to be any games going on. Is it invitation only or something?

It might be because the game isnt that popular, and doesnt have good reviews. I am kinda sad, I was hoping for a modern naval simulation, looking forward for great battles against human players and have some kind of league or fleet going! Arr...

All you can do is log onto the game lobby and either set up a game for someone else to join or else join a match offered by someone else.

I've tried a few MP matches, but most of my attempts end with the server crashing due to sheer weight of numbers in missiles (I think).
