Last week we reported that Rebellion had bought a number of former Vivendi Games properties from Activision Blizzard but it seems Activision has kept the rights to a number of those games as well. Today five former Sierra/Vivendi Games properties are available to download via Steam under the Activision publishing banner.

Among the games listed are the Space Quest Collection and the King's Quest Collection, each collecting the classic Sierra adventure game series. Also included are two more recent downloadable titles, Aces of the Galaxy and 3D Ultra Minigolf Adventures. Finally the hardcore first person shooter Timeshift has also been added. All five titles are available for 25 percent off their normal Steam prices until June 30.
