[L4D2] There are two different versions of the game

[MyNameWasTaken]

I just purchases L4D2, and now there are two different games in my library. There are "Left 4 Dead 2 Beta" and "Left 4 Dead 2 (Beta)." What's the difference, and why are there two?

Left 4 Dead 2 (Beta) is what you want to play, since it is the real version of the game (This is what also the Windows and Mac users are playing).
Left 4 Dead 2 Beta is where Valve is testing new stuff out (however there is nothing new currently in it)

You're too dumb to know.
