POLYBIUS:
There is an urban leyend of an arcade game of a game center in Portland,and it was programmed by Ed Rottberg.The game consisted in a spaceship that had to destroy different enemies in each level.The game became so popular,and some people were adicted to it.In some time,the people that played the game started to experiment some symptons like neurological afections,dizziness and vomits and also subliminal mensages like "kill yourself","no thought","honor apathy"and "no imagination".
People that went to that game center,often saw two men in black,that when the game center was closed took notes of the effects of it,this made people suspect that the teo men in black were part of the government.
One day,it was comfirmed the death of a player of Polybius,and a few days after,the videogame dissapeared from the game center forever,maybe because of the men in black,that it is supposed that they stole it.
