Logo: In a letterbox format, designs of a gear, along with several details in it as well. These violently shake and flicker away from the screen. Among these is a grey background with white splotches and and broken spots. In the middle is a black box with a close-up of an rusty gear. Above it is "gearbox" in a messy typewriter font and "software" in a plain font expanding the bottom of the box. Throughout most of the logo, it appears in mostly close ups, with occasional splotches and gear blueprints, with boxes having the company name in it. Near the end, the logo then gets fully revealed with it shaking harder and harder, all before cutting to black. FX/SFX: The logo flickering and shaking. Music/Sounds: Harsh working sounds, starting with two dull hammering sounds, then four repeating hammering bangs joined with gearbox noise, then repeated gearbox working without hammers. Availability: Rare. Appeared on two add-ons for Half-Life, Blue Shift and Opposing Force. Also appears in a demo for the PC version of 007: Nightfire, Tony Hawk's Pro Skater 3 and Halo ports for Windows. This was not seen on the PS2 version of Half-Life, which instead used a still logo alongside the Valve and Sierra logos. This is not on the Steam version of Half-Life: Blue Shift. Editor's Note: None.
