Recently I discovered Cold Waters and someone pointed me to this forum where I could find some mods.
It's been a long time since I last played a subsim, but nevertheless I enjoyed several of them during the last decades.
I started with Silent Service on my ZX Spectrum. I remember Aces of the Deep and listening to "Lily Marleen" while diving in Silent Hunter.
I also enjoyed Sub Command and the last one I had was Dangerous Waters. So while looking for some flightsim videos on YT I found a video of Cold Waters and decided to give it a try.
