The same disc, though with different disc labels, was distributed throughout Europe and Australia with OPM magazines. The Polish version contains the standard European disc titled Best Horror Games Ever Demo, and came in a cardsleeve. Known variations were released in the UK, Italy, Spain, and Australia.
The disc contains a playable demo of Silent Hill, the censored Resident Evil rolling demo from 1996, and a Dino Crisis demo. The Silent Hill demo is not the same as that which was included with Metal Gear Solid, but a later demo.
