Pros:

The reloading sound is amazing, very realistic instead of the Left 4 Dead 2 sounds.

It fits the guns reloading very much.

Cons:

The sounds for the SCAR and Silenced SMG are not that good in my opinion, but GCF Scape should fix that ( -0.1 )

Conclusion:

The mod is amazing and I'm looking forward in to using it more/

Pros:

Many funny voice lines like Nick saying "Your mom's car"

Useful commands instead of taking the time saying "help!" in chat.

Best spamming vocalizer out there.

Cons:

It may take others a while to know where to find the launch options (not me, but others yes) ( -0.1 )

One of the binded keys are to F12 which is used for screenshots, meaning you have to use GCF Scape to open the file in go into the .cfg ( -0.2 )

Conclusion:

Amazing mod, to me in my opinion it has very little flaws and is amazingly fun to spam the hell out of, nice work.

Pros:

Nice model.

Amazing animations.

Would fit L4D2 in my opinion.

Cons:

If It was for the UZI I would use it. ( -0.3 )

Conclusion:

It's okay, but I wouldn't really use it since it isn't for UZI. Good job though.

Pros:

The music is amazing, love it.

The music fits L4D2's atmosphere.

Cons:

Some music like the Parish's start didn't fit so well, but using GCF Scape and removing those sound files makes no problem ( -0.1 )

Conclusion:

The music fits very well, I'd recommend it for people who would like some fitting music for a zombie apocalypse.
