"Left 4 Dead 3," the successor of "Left 4 Dead 2", is rumored to be in the works.

A lot of fans have been waiting for the release of the third installment of the "Left 4 Dead" franchise. The last title of the gaming series, "Left 4 Dead 2," was released in 2009. New reports surfaced that "Left 4 Dead 3" will be launched in 2017.

Even though game developer Valve remains tight-lipped about the release of "Left 4 Dead 3," there are rumors that the development had long started and it could be introduced in 2017.

According to reports, a Valve employee named Tristan Reidford apparently had to show a tutorial for the new Destinations virtual reality (VR) platform on Steam. It was supposed to be for a new app that gives players the power to explore the real world and imaginary locations using the VR technology. But it seems that fans' attention is focused on something else. A lot of fans realized that the screenshots in the presentation have a folder with a name "left4dead3."

Although the image has been saved by various online sources, the original source has since took the image down and has been replaced. There was no explanation on why they had to change the photo, but it could mean that "Left 4 Dead 3" is really in the works and they had to keep it a secret. It could also mean that the game developer just does not want to magnify the rumors, especially if nothing has been set yet.

Despite the numerous rumors about the much-awaited "Left 4 Dead 3" for the past years, Valve has remained mum about the third installment. Even another much-awaited game "Half-Life 3" still has no update.

According to other reports, the Valve video games are still active and not just the Steam platform since director J.J. Abrams is still pushing through with the film version of Valve's own "Portal."

More details on "Left 4 Dead 3" may soon be announced.
