This is a .7z archive that contains all the files needed to install the Half-Life 2 Beta Mega Build. The total install size is 14gb with everything installed. This will work without Half-Life 2 installed, and does'int need Steam to work. After opening the .7z archive, extract the "Half-Life 2 Beta Mega Build" folder to wherever, then load autorun.exe. You can even burn this on a disc by burning the contents of this folder onto a dvd.
