If you could classify Ploing2 into a category it should be a pinball game. But this doesn`t cover everything, as there are also large doses of Arkanoid, pong and even pure style arcade.
The aim of Ploing2 is to go from planet to planet. Within each planet you must destroy, just like in Arkanoid, each of the constructions there, and like in pinball you get higher scores hitting the different elements you find. All the graphics are in 3D, and it is outstanding above all for the luminosity of the graphic effects when something is hit.
To work correctly you need to previously install
DirectX 7.0 or later.
