It's been more than 10 years since "Half-Life 2" was released, but fans of the franchise still continue to hope that a third installment will be arriving soon.

Developer Valve has been silent when it comes to updates about "Half-Life 3" that some fans slowly start to believe that a sequel may never happen. The lack of updates from Valve is the very reason why it is believed that "Half-Life 3" will never come.

There have been rumors – which have become even stronger recently – that Valve is already hard at work developing the next "Half-Life" game. There were even speculations that the third installment will be released sometime in 2018, which is the original game's 20th anniversary. However, it should be noted that these are just rumors and as mentioned, Valve has been quiet and has never made any confirmation about a possible "Half-Life 3."

At one time, a fake Twitter account was also made to announce the release of "Half-Life 3," but that too had been proven to be false and was only made to get fans hyped up. Reports also mentioned that one of the reasons why "Half-Life 3" isn't happening is because of Marc Laidlaw's resignation. Laidlaw had a major role in the franchise, but with him leaving the company, it only meant that there isn't likely a future for the much awaited sequel.

Despite the lack of confirmation about a sequel or hints pointing to the ultimate end of the franchise, there are still those who cling on to hope that one day Valve will decide to develop the game. Rolling Stone's recent article implied that "Half-Life 2's" cliffhanger ending is also one of the major reasons while fans are shouting for a sequel. Fans are dying to know what happened to game protagonist Dr. Gordon Freeman.

This won't be answered unless there will be a "Half-Life 3." It appears though that this question will just have to remain unanswered for now.
