It looks like "Half-Life" gamers are itching for the third installment to Valve's popular first-person shooter videogaming series even if the details about "Half-Life 3" still remain as unavailable as ever.

Four days from now, the "Half-Life" videogaming franchise will be celebrating the ninth anniversary of its second videogame installment, and with the anniversary date drawing near, Game n Guide reports that gamers have begun to express frustration over the absence of "Half-Life 3." Given the nine-year gap since the release of the second "Half-Life" game, it seems like gamers have begun to expect Valve to finally give word on "Half-Life 3."

Though Valve hasn't issued any statements on a third "Half-Life" installment, rumors have begun to spread that the game could come out sometime soon with a few reports suggesting that "Half-Life 3" could very well be at the final stages of production.

According to a report by University Herald, Valve had originally planned to work on "Half-Life 3" after "Half-Life 2." However, the developer had changed its mind and decided that the third first-person shooter installment would be divided into three small episodes. Since then, however, fans haven't heard a word from Valve about the third "Half-Life" game. Back in 2012, an alleged concept art for the so-called "Half-Life 2: Episode 3" made its way to the Internet. Since Valve never confirmed the content of the leaks, nothing became of the third episode of "Half-Life 2."

With all these rumors leading to nowhere, fans are now beginning to worry whether they're going to see "Half-Life 3" at all. Despite the grim circumstances, however, speculations have also begun spreading that the third "Half-Life" videogame might come out two years from now in 2018 in order to celebrate the 20^th anniversary of the franchise. If not, it could come out in 2028 for the 30^th year milestone. Fans will just have to wait and see.
