Mega 6 Vol. 3 is a compilation of Sega Mega Drive games released in PAL territories during 1995, and was included as part of the console's late official bundles. The cartridge was the final release in the series of Mega Games compilations, and contains 6 of Sega's most successful games from the early days of the Mega Drive.
It is the only volume of the Mega Games 6 series to introduce a new game to the Mega Games range, and the only Mega Games release to use the shortened Mega 6 title. The game came with individual instruction manuals for each game rather than integrating them all into a single manual. This compilation utilises the standard game selection screen seen in previous Sega compilation releases, including the Mega Games series, Classic Collection, 6-Pak and Sonic Classics.
