First run out in the sub. I took U-69. Acoustic pinging is not as easy as it seems but it allows torps to ignore the torpedo belt armor of ships. I got it once and took down a BB. You can also dumb fire torps at the depth you are at. I came out victorious somehow. lol
Basicly… I have to fight on a map with subs… before I can get a sub. For 7 days.
It says: Select Submarine Battles, select any Tier VI ship, and fight against submarines!
To stand at the helm of a submarine yourself, you need to collect and use Submarine Tokens. These Tokens will be credited upon your first login each day during the run of Submarine Battles. You can exchange Submarine Tokens for random bundles in the Armory. One of the seven available random bundles will drop three 21-day rental submarines, each with a special 19-skill-point Commander. The remaining bundles will drop 500 Coal each.
Right, you have to do daily logins and then you’ll get the “submarine token” that will unlock the 3 subs with commanders. It’s RNG I believe, so you might get it on the first shot – or like me – took me 7 days to unlock the subs.
Once you unlock the subs, there is a special battle type for subs where you then get to pick 1 of 3 subs you unlocked.
