Half-Life: Opposing Force Easter Egg - Gearbox and Valve

This one's pretty obvious. On the pit worm level to drain the toxic sewage you have to switch on the gearbox and the valve.
For those of you who doesn't know what this means, Gearbox was the company that made Opposing Force and Valve was the company that made the original Half Life.

There is also a Steam Vent that has to be opened. Steam is the software Valve use to sell their games on-line and also delivers updates and control of their on-line games.
