Pros:
Weapon firing sounds are from BF 3, course they are great Additional option to download sounds files separately (non vpk.) (link in the changelog)
Cons:
90% positive that the reload sounds are not from BF 3 (can't be helped i suppose, BF 3 reload sound times do not match those of L4D2) Due to no matching reload and firing sound, BF 3 immersion is not at its best (then again if you want total immersion you can just play BF 3 itself) some of the reload sounds sound lackluster, particularly the shotguns occasional distortions even after snd_rebuildaudiocache and snd_updateaudiocache
Conclusion:
An Overall Very Awesome sound port. I was going to rate it an 8 due to lackluster reload sounds but the option to download and install the files manually is invaluable, giving freedom of customization. Kudos authors for being the first ones to upload the sound files separately. pop champagne*
