Dark Seed II is a psychological horror point-and-click adventure game developed and published by Cyberdreams in 1995, and is the sequel to the 1992 game Dark Seed.

Although Mike Dawson saved the world from the "Ancients" in Dark Seed, the experience causes him to undergo a mental breakdown. He returns to his childhood hometown of Crowley, Texas in an attempt to regain his sanity, and moves in with his mother. A year goes by, and Mike is still suffering from serious mental scarring and memory lapses. Worse, Rita, his girlfriend, is found murdered after their high school reunion, and the entire town of Crowley seems convinced that Mike is the culprit, with the exception of his friend Jack. It is evident the "Ancients" have returned, and the only way for Mike to clear his name is by venturing between alternate realities and solving their mysteries, while simultaneously stopping the Ancients from taking over the world.
