i have heard about
 

i once long time ago heard someone in here saying he was playing a sub sim, and on his sonar he was able to hear a wale once :ping: :D can anyone tell me what sim that might be ? sounds awesome ! see you on the water :arrgh!:
BTW when do people start to play online is SH4, wich sub game is most ative online:hmm2:

Well, you used to be able to hear whale song on the passive sonar in Sub Command if the scenario builder had put a pod in. I guess Dangerous Waters has probably got whales in too, but it's a long, long time since I played DW so I can't tell you for sure.

Yeah,,DW has a lot of biologics..whales are singing!!!

Could also be SH3/4/5 with mods...
