Fans are still kept in the dark when it comes to the details of "Left 4 Dead 3." Valve has remained silent even about the existence of the sequel.

Prior to the 2016 Electronic Entertainment Expo (E3) this month, rumors about Valve making an announcement about the sequel at the event made the rounds. However, with E3 on its last day yesterday, the developer still didn't drop anything concrete.

It seems that fans are yet again clueless about the game's fate. According to iDigitalTimes in a report from 2013, the game is already in development, but how much longer should fans wait for the sequel? 

At this point, all that's been said about "Left 4 Dead 3" is based on pure speculation. The latest reports suggests that the game will be available by 2017. Express reported early this year, what is believed to be the closest thing to concrete details about the game since its predecessor came out in 2009.

The publication noted that in "Left 4 Dead 3," there will be four new characters on board – three males and one female. The male characters are comic book nerd Keenan, Kenpo fighter Garrett Jr. and a gangster named Irvin. The female lead is said to be named Katherine.

More interestingly, the new game is also said to feature six new separate campaigns. They include Cliff-Hanger, Early Destination, Crashland, No Mercy, Inquisitor Land and Impasse.

These bits of information may be a delight for fans who have been clamoring for the release of "Left 4 Dead 3." However, Express didn't explicitly name its source, so these reports are as good as rumors and should be taken with a pinch of salt.

"Left 4 Dead 3" is not only a Valve title that has been rumored for years. Fans are also looking forward to the announcement of "Half-Life 3." "Half-Life 2" is already a decade-old but still fans are anticipating for a release. But between the two projects, "Left 4 Dead 3" is said to the title that's likely to have a future.
