Still early early alpha build, no sound and barely any gameplay.
You bank movement and the submarine will move 1 step/sec. Every move will increase the heat faster than it will dissipate it. You move with WASD.
Pressing tab will switch between world view and sonar view. In sonar view you’ll have a Bearing Sonar view. To increase the distance you detect enemies on you press W while in Sonar view.
At the moment everyone starts at the same place, there’s no hinderance to the way you move or anything. Like I said, it’s a VERY early alpha.
