Beta 6g is available for Free Membership download.
The manual is in the root directory. Free Members: you will need to download all three 6G packs. Extract sounds and textures to main, just make sure sound and texture directories are in the main and not some subfolder where they won't work.
Ignore the txt file, just my notes in there somehow.
On a side note, the English.str file in Word is like 527 pages.
