With "Half-Life 3" rumored to be in the making, fans also speculate the development of "Left 4 Dead 3" as well. With rumors of possible leaks to Valve's collaboration for a virtual reality platform to moving to a new office space, it would be possible that it would affect the development on the next "Left 4 Dead."
Speaking of moving to a new office space, it was reported in an earlier article from PRWeb that Valve will be moving to a bigger space in the Lincoln Square Expansion in Bellevue, Washington. Since the area is still in development, the real estate agency Kemper Development Company mentions that the video game company would be moving there around May 2017.
This may be an indication that the company would be focusing more on other projects, such as big titles like "Left 4 Dead 3." It could be possible that Valve is steadily growing and that a new and bigger office space would help in accommodating more manpower in developing the sequels.
Digital Spy mentioned earlier that "Left 4 Dead 3" might be released as soon as next year. The game was rumored to have four new protagonists to be 24-year old caucasian Katherine, African American gangster Irvin, famous Kenpo fighter Garrett Jr. and comic book nerd Keenan.
For the setting, there are six campaigns that have been named: Crashland, Impasse, Inquisitor Land, Early Destination, Cliff Hanger and No Mercy. The third game is supposedly set a one month after outbreak, which is somewhat earlier than the events of "Left 4 Dead 2."
Earlier reports mentioned Valve employer Tristan Reidford unintentionally leaking "Left 4 Dead 3" during one of his tutorial videos for the Destinations Workshops Tools, an editing program for Valve's source material. In the video, while Reidford demonstrated the software, there was a small glimpse of a folder labeled "left4dead3."
Again, until any actual news will surface, fans can only hope and wait.
