A moored magnetic mine is a naval mine attached to the sea floor that explodes when its mag alls connect to a ship. This mine is packed with warheads that will explode if its mag alls connect to something, or if fired upon for long enough. (I've tested it with the machine gun, so I'm not sure if handheld weapons have the same effect) It also features a system that will automatically raise the mine to whatever depth needed, in waters as deep as 150m. This mine works best when there are only about five of them, as any more than that tends to lag the game.
I wanted to make a naval mine that worked for ships that weren't quick enough to breach the impact threshold of the contact mine. Currently working on the S.S. Prydain Fawr.
