Pros:

More dialogue
Fun to use

Cons:

Look command
Virgil command
Specific dialog

Conclusion:

This is fun to use and I do like the extra stuff. Most of the survivors have a decent amount of dialogue and its wonderful and all but some don't even work. When a L4D2 survivor(s) uses "Virgil" command he starts shouting and its really annoying. 
It would be better if survivors when they use "look" command towards weapons, grenades, health, etc they'd say whatever it is they're looking at but instead they just say "look, check this out, look at this."
Possibly to fix that for future?

Pros:

Realistic
Correct eye for each survivor

Cons:

Conflicts with Bill's melee attachment

Conclusion:

This mod gives the survivors life instead of being dull. Ellis's eyes I do like but I always imagined them to be cerulean or sapphire colored. As for Blll I'm not sure why it only conflicts with his melee attachment. Nonetheless good job.

Pros:

L4D2 on L4D1
Retains L4D2 music, songs, etc
Looks much better on L4D1

Cons:

No Bride Witch
Supplies and ammo was scarce
Map 2 crescendo event
Survivors don't talk

Conclusion:

It's a good campaign, I enjoyed it for the most part with the exception of Map 2 crescendo event. The water doesn't have trending effect causing the survivors to walk the whole way. Way to difficult to even reach the ladder with only a pipe bomb before the event starts especially on a higher difficulty. Since the survivors don't talk it's really quiet, just making awkward faces at each other but I don't mind since the dialogue won't make sense even if they talked to one another. Overall I liked it, hope to see more on your work. 

Pros:

~New songs
~Easter eggs
~Fits the L4D universe well
~All SI music are definitely more dramatic

Cons:

~The Sacrifice, Dead Center, and Hard Rain don't have intros (don't mind because it still has the essence of L4D)
~Tank music and Spitter's music
~L4D2's rescue music sounds very similar to TheMonsterWithout

Conclusion:

I really love this music mod, not only is it interesting its just wonderful to hear a collaboration of Easter eggs mixes in wonderfully in a universe such as this one. As for the Tank and Spitter's music---It plays normal offline but when I play online Tank's music is silent unless its a finale's Tank. The Spitter's music doesn't play at all online, just silent regardless of finale or not. I'm not sure it this is just me but nonetheless I highly recommend this mod, the whole thing is definitely worth it.

Pros:

Detailed
Minecraft
Intro & Music

Cons:

L4D1 Survivors

Conclusion:

I really enjoyed the campaign but I would have loved to play as L4D2 survivors.
