Solid Sharkey's Polybius Page
The latter had a text stating: "Ever hear of that game that induced amnesia and caused kids to wake up in the night screaming for no reason? Neither had I, until someone emailed me asking for a copy of the ROM." When accessing the page, an animation of a zombie from Fatal Frame, with the word "Polybius" near the top of the article, appears along with a loud scream. In addition, the site provides some information summarizing the story of an urban arcade game called "Polybius" except for one part that reads: "Interrupting the game with a screaming horror like the one on the top of this page (which probably just cost me a few friends.)" The page existed until 2013.
NOTE: The following website contains a screamer!
