Pros:

That poster.
Custom melee weapons.
Intro is decent, better than most.
Custom music.
Great level design.
Atmosphere is believable.
Third level is amazing.

Cons:

I only got to the third level. (-0 points)
Noticeable lag on the starting point of the first map after the intro. (-0 points)
Backtracking was needed in some parts, but it wasn't that big of a deal. (-0 points)
Invisible specials and zombies in some parts. I disabled all campaigns and infected skins before doing this campaign. (-0.5 points)
Melee weapons don't have custom icons. (-0 points)
Runtime errors completely ruined the entire experience, as when I get one, even if I'm in the saferoom, I have to close and reopen Left 4 Dead 2. That poses a big problem if I'm doing in on solo, which I wasn't, but still. (-3 points)

Conclusion:

I have to admit, the campaign is amazing, but with all the problems I ran into, it's barely even enjoyable or playable. I couldn't even finish the damn thing. This hasn't happened with other custom campaigns before, even ones that featured new weapons or L4D1 characters.

I would love to give this the 9.5 or 10 it deserves, but it just can't due to the amount of troubles.

Pros:

This actually fits the game, although I honestly just ignore most pony skins.
A good alternative to the red first-aid-kit.

Cons:

Not a brony, doesn't matter.

Conclusion:

Good skin. Definitely for bronies, but it can also appeal to non-bronies alike.

Pros:

Portal fan is amused.
Awesome model.
Awesome textures.
FPS arms.
Other stuff that's awesome.

Cons:

None.

Conclusion:

And for all the people asking for a name change, you have another mod conflicting with the custom names. Make a new mod involving closecaption_english.txt.

Pros:

Love. Basically everything is amazing.

Cons:

None.

Conclusion:

Awesome mod. Probably the best one for Ellis at all.
And now we just need an Advanced Suit mod...but whatever.

Pros:

Awesome textures.
Awesome animations.
Awesome sounds.
Awesome model.

Cons:

Compiled my own version of the SCAR-Lestia's boltpull anims on these textures, so none, really.

Conclusion:

Better than a pony skin, for sure.

Pros:

Unique.
Almost like Tower Defense.
Awesome detail.

Cons:

Zombies need to come in separate hordes, not all at once.
It's possible to shoot and shove while building, why not reload?

Conclusion:

Awesome map, and a unique map at that.

Pros:

Again, another awesome Halo mod.
Great detail.
World-model looks and works fine.

Cons:

Due to the riotshield being cut from the game, it is a bit buggy in various areas, but I'm pretty sure that's impossible to fix.

Conclusion:

Great mod overall.

Pros:

Halo Assault Rifle, and I don't really need to say more than that.

Cons:

All of my cons are probably gonna be fixed in later updates, but I'll list them anyway:

- invisible clip while reloading both in first person and third person
- bullet counter doesn't go down (can deal)
- Arby's animations don't fit with this type of rifle

Conclusion:

Great mod, recommended for anyone.

Pros:

Best mod for Coach ever.
FPS arms
Awesome model

Cons:

Bug actually fixed now, so none.

Conclusion:

Not going to remove points for this, but runtime errors. Any help here? Just keeps popping up in middle of the game saying 'Runtime Error!'. Need help? <3

Pros:

Pretty much looks like the exact same thing from Halo, sound effects or not.

Cons:

Empty.mpeg

Conclusion:

A great mod for non-Halo fans and Halo fans alike.

Pros:

Fixes the broken third person shoulder in the game

Cons:

None

Conclusion:

That's about it, really. I play with third person shoulder a lot, so...yeah. Thanks.
