Pros:

Amazing Model
Kick a** textures
Extreme detail
Arby's animations

Cons:

The grip is unnecessary, clips threw the hand too
No flashlight attachment

Conclusion:

Very well done MOD and "the" ultimate silenced SMG replacement!

Pros:

Beautiful Model
Once again great textures
Looks really nice in the survivors arms
Classic white HUD icon 
No bugs

Cons:

Big sister is watching me.. :c  (spray)

Conclusion:

I sense a' SPAS-12 No Stock' is coming..!

Pros:

Amazing Model
Great Textures
Classic white HUD Icon
No Bugs

Cons:

Uses Arby's old Auto Shotgun animations, not the dark friendly animations

Conclusion:

Not not much to say other than "it's good and you should download it." The 2nd nicest SPAS I've ever seen for L4D2.

Pros:

Perfect Setting
Great Detail
Not to hard not to easy (For me)
Fairly easy to navigate
Gives you the chills 
Good amount of items
Ending 

Cons:

Levels are too long.

Conclusion:

Get this map, play it and keep it forever. I put this map on my top 10!

Pros:

Everything

Cons:

Nothing

Conclusion:

This map is perfect. It has so many things that the official maps don't have. It really is something special.

Pros:

Easy to Navigate 
No lag or long loading Times

Cons:

Lack of weapons at the Beginning 
Too Short

Conclusion:

I like this map, the only major thing is that it is too short.

Pros:

Very cool & empty creepy atmosphere
A Dark snowy map

Cons:

Some areas look the same
lack of weapons mostly Auto Shot-Gun. That's probably bad luck first time playing
Cruel finally

Conclusion:

I like this map with the dark winter atmosphere. Just got lost a lot and never found my favourite weapon till the end.

Pros:

No Mercy, Crash Course and Death Toll are great improvements.

Cons:

Dead Air and Blood Harvest's picture are not in the centre of the screen. Dead Air's back ground is plain.

Conclusion:

Make a better back ground for Dead Air.
