Cold Waters - E1 - Chinese Campaign

Introducing the most enjoyable submarine game I have likely ever played: Cold Waters. In this first episode, we are 2 missions deep in the Chinese campaign, based in the year 2000. I have selected the Seawolf SSN-21 for my platform for this campaign. The difficulty is set to elite (max) for as much realism as we can get.
We have deployed a seal team in proximity of Yulin Harbor and are exfiltrating the South China Sea back to re-arm at our forward base in Guam when we encounter a sonar contact within 25000 yards.
