Pros:

Everything. Sounds amazing, looks amazing, feels amazing. By far the best mod I've every downloaded for L4D.

Cons:

The shells on the side. I think they look stupid not all facing the same way, but it's not a big deal.

Conclusion:

Best weapon mod made yet. You will not be disappointed when you download this mod.

Pros:

-Gorgeous
-High Quality

Cons:

None

Conclusion:

I've been using this forever now, just wanted to review it and try to let everyone know how great this mod is. Try it out, you won't be disappointed.

Pros:

Good length of maps
Challenging
Fun
First maps were interesting
Witch room can be really funny

Cons:

Bots had some trouble
Witch room can be really frustrating
The finale was really boring and drawn out

Conclusion:

It was good at most parts, but the finale was kind of drawn out and boring. It got to a point where it was just grab cans run to heli pour grab more cans repeat.

There were a lot of weird things in the campaign that I liked. Find them for yourself as you play through.

Pros:

-Exact Health of teammates.
-Looks Good

Cons:

-Don't like the Survivors profiles (?). That's more of a personal thing though so I won't hold it against you.

Conclusion:

It's very nice. Much better than default. I will not use this one because of the survivor pictures but it is still a good mod. Nice job.
