A few days ago, a tech demo called Half-Life Alpha became available and someone went ahead and took some footage of it. To put this in perspective, the early demo was originally created in 1997, one year before the seminal shooter was actually released. As a result, the footage looks really rough, the character models have this grotesque vibe going on and at one point during the gameplay footage a robot from the Robotech anime series makes an appearance.
It took sixteen years for Half-Life Alpha to see the light of day. Hopefully, Half-Life 3 will come out sooner than that. Right Valve? Right?
