1. Take everyone off deck watch and empty the sensors room. You don't need those sissys freaking out everytime they see a potential collision hazard or enemy anyways.
2. Yes, that's correct. You need to not surface in order to launch torpedoes from a submerged position.
3. You won't be able to recover the dingy or the men. They've gone native.
3a. Command will notify you of your new orders when they are darn good and ready. You aren't the only sub in the fleet, ya know!
4. Figure out which way they are headed. Get there before they do. Wait.
5. Escape. The key, not panicking and opening the hatch while submerged in an effort to.
6. The little squre thingy is called a desk. It's for placing your medals and pictures on.
7. As fast as you can. Turning helps.
Hope this helps! (Or at least makes you smile
)
