WWII tactical submarine combat on your iPad!

Take command of a U-boat prowling the Atlantic in search of enemy convoys to sink. Sneak past the escorts and torpedo the transports. Or surface and use your deck gun in a night attack.
When the escorts come after you, drop decoys and sneak away before they can crush you with their depth charges.
