What is Cold Waters?

- +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
