Half Life fans are currently very active in various gaming forums. This is because they are attempting to force an announcement on Half Life 3 out from Valve.
In detail, the Half Life fans are flooding the internet with conspiracy theories. They are hoping for a theory to come out spot on and this will force Valve to announce on Half Life 3.
Apparently, the fans are inspired by Portal 2’s announcement. Valve announced Portal 2 after a fan discovered an Easter egg of the game in and ARG title. The fan wrote about it and it got Valve admitting that the game is in development.
For the non-Half Life fans, this may sound like a ridiculous attempt. Then again, the Half Life fans have suffered more than a decade of wait so they got nothing to lose.
