Quake 1.5's sound effects had room for improvement, especially with the Quake re-release now out. This pack is a MAJOR overhaul/upgrade for the sound effects for better quality and even new sound effects that seemed better fit for Quake 1.5.
To install, DELETE the "sound" folder from the "q15.pk3" (you can open pk3 files with 7-zip or pakscape); then drag the "sound" folder provided with the zip file into the pk3 file. MAKE SURE YOU ALSO HAVE QUAKE SOUND BULB!
This may include unwanted files, but those will be removed over time.
