We will post the system requirements when we'll reach the beta phase, we are too early in the development now.
Here is one of the special views of the aquanauts, the electrosensors view:
In the final game the view will be restricted to the area near the aquanauts or the crab-drone scouts. Nevertheless it is impressive and it looks great in the game, with all sort of sparks glowing all over the place.
You can note that the alien UFO is absorbing the electric current and so will be some alien types, making them easy to spot.
