What is Cold Waters?

For you if...

  • +you like tactical combat built around detection and evasion
  • +you enjoy learning naval tactics without complex controls

Not for you if...

  • −you want fast action without patient tracking and planning
  • −you prefer commanding surface ships rather than submarines
  • −you want a forgiving game that rarely punishes mistakes
