Update: Activision has now confirmed that Sierra is coming back from the dead and will serve as an incubator within the publisher bringing top indie games from third party studios to digital platforms like PlayStation Network, Xbox Live and Steam.

Two initial efforts include a reboot of the classic King's Quest, noting that the IP is being "fully reimagined" by The Odd Gentlemen (The Misadventures of PB Winterbottom), with a release planned for 2015. The second title is Geometry Wars 3: Dimensions, developed by Lucid Games.

Original story is below:

The last few years have come along with a number of video game publishers and studios closing like THQ and the messy situation surrounding 38 Studios. One of those companies that faded away was Sierra Entertainment. The company was responsible for titles like the Space Quests series as well as lending a hand with publishing on the Half Life games, Spyro and Crash Bandicoot.

Formerly known as Sierra Online, the company was essentially shuttered when Activision merged with Sierra parent company Vivendi in 2008. After what many considered a long list of sub-par releases, Sierra appeared to have disappeared for good. But now, on the eve of Gamescom 2014 in Cologne, Germany, the company looks to be making a comeback.

In the video below, we see a faceless hiker making his/her way towards a large snow covered mountain in the distance, before the camera pans out to reveal a new Sierra logo. While there is no confirmation as to whether or not these are art assets from an upcoming title, some believe they are. Either way it likely safe to assume we will be seeing something new from the company this week in Germany. The video comes by way of a new Sierra teaser site promoting Gamescom 2014.

While it likely won't be long until we find out more about what Activision and Sierra are up to, you can check out the teaser video below in the meantime...
