Danger from the deep (aka dangerdeep) is a Free / Open Source World War II german submarine simulation. It is currently available for x86-32/64 Linux, Windows, OSX, and FreeBSD, but since it uses SDL/OpenGL it should be portable to other operating systems or platforms. (If anyone whishes to port it, please contact us.) This game is planned as tactical simulation and will be as realistic as our time and knowledge of physics allows. It's current state is ALPHA, but it is playable.
