Valve has a history of leaving their most successful franchises without their third installment, so much so that it has become a running gag over the years. A recent leak that hints to the possible existence of Left 4 Dead 3 may change that.

The leak came from a tutorial for Valve’s Destinations Workshop Tools by Valve concept artist Tristan Reidford. In the tutorial there are several screenshots, in one screenshot a folder can be seen that reads ‘left4dead3’ in the file explorer.

The image has subsequently been removed and has been replaced with an image that omits the Left 4 Dead 3 file. The odds are that this is a joke that Valve is playing at our expense. Inspection of the ‘left4dead3′ folder has found that one file in the folder was named ’08_directory_fun.png’ which gives the joke angle more traction.

Even with the possibility of it being a joke, that hasn’t stopped fans from investigating Reidford’s Steam Profile. The concept artist had been playing Left 4 Dead 2 more lately, with a total playtime of 49 hours played. For some people that is all the evidence they need for the Left 4 Dead 3 rumour to become a reality. This may be the first leak of the long awaited sequel or it may just be a joke that got taken seriously, only time will tell.
