Pros:

- It exists.

Cons:

- Stretched limbs
- Poor texturing
- Very dark

Conclusion:

Looks awful and clumsy, and the characters' limbs are literally sticks.

Pros:

- Limbs don't clip during animations
- Good looking
- Matches Minecraft Survivors

Cons:

- Limbs clip together upon death
- Out of place in default campaigns

Conclusion:

Definitely matches with the various Minecraft-themed mods on the site, and has no noticeable errors.

Pros:

- Funny
- Good looking model

Cons:

- Hitbox isn't changed

Conclusion:

This pack may come with a funny change for the CI, but the major downside of this is that the hitbox isn't changed. You'll find yourself having to shoot the air instead of the cat itself, but it can be easily overlooked.

Pros:

- Brings back fond memories of L4D1

Cons:

- Missing gore
- Low quality
- Does not fit in with the graphics of L4D2

Conclusion:

Good if you liked the L4D1 zombies, but it clashes a bit with the enhanced graphics of L4D2.
