Is dangerous waters dead game?

I really like dangerous waters. It feels great to play even if its a little dated.

But it also seems like the kind of game that is built for co-op. It can be difficult (al least for a beginner like me) to jump from station to station in good time without having my DD blown out of the water in combat.

Does anyone still play co-op? or is it dead? or is there a modern game that people have switched to?
