Key Features of HMS Alliance

Unlike the researchable British submarines, Alliance has access to both acoustic and standard torpedoes. The acoustic torpedoes have a shorter distance at which they stop homing, as well as improved turning speed towards pinged targets, but they are extremely slow, giving an opening for enemies to evade them. They also deal low damage. Like the researchable British subs, Alliance has an impressive dive capacity and good speed, but a small HP pool.
