Zak McKracken: Between Time and Space

Zak McKracken: Between Time and Space is a point-and-click adventure game, originally released in 2008. It is an unofficial fan sequel of the 1988 adventure game Zak McKracken and the Alien Mindbenders and was developed without the involvement or approval of LucasArts. It contains numerous references to the original game, including easter eggs. The game took more than seven years to complete and has since been further developed, with a director's cut released in May 2015.
