Tornado is the clone of a C64 game. I know that was a long time ago, but maybe somebody still remembers that times.
The goal of the game is to destroy the opponent's house with certain weather phenomenons: rain, snow, hail, lightning and tornado. The game can be played together (two players), against the computer (or two computer players against each other) or over a TCP connection.
