Jampack was a demo series from Sony under its PlayStation Underground brand.[a] It was used to advertise and preview upcoming and released PlayStation and PlayStation 2 games through demos and featurettes.[1] It often included imported game demos, behind-the-scenes videos on developers and games, as well as cheat codes and saved games. Jampack often served as a preview for the PlayStation Undergroundonline magazine.[2]
Many of the later PS2 Jampack volumes were issued with the option of a counterpart that removed or replaced any demos for mature-rated and some teen-rated games, essentially serving as a clean version of the compilations.
Notes[]
^The "Underground" name was not used on the first two Jampack discs, which were simply titled Jampack Vol. 1 and Jampack Vol. 2.
