Where does the name "tau cannon" actually come from?
It's called the gauss gun in the files, but I have always called it the "tau cannon" because that was always what I perceived as the "real" name (it being based on a particle accelerator and all). But, what does that name actually come from?
It's not like it's ever named in-game, and like I just said, the game's data calls it the gauss gun.
EDIT:
It is called the tau cannon in the data of Opposing Force, in deathmatch, and in Half-Life 2
