Pros:

Great Models
Not too many Bugs
Very well animated

Cons:

No Custom Audio
Pinkie Pie having Coach's voice can be a little...odd
When using the chainsaw, my screen 50% Hoof
Models are a little large, so friendly fire is common. 

Conclusion:

Make the models a little thinner and smaller, if you can, possible get a few audio clips in, if you can. Other then that, this is an excellent fan mod for any brony. The only thing keeping it from a 10/10 is a rather annoying chainsaw bug, and friendly fire. 

Pros:

The Skins seem clean.

Names are edited.

Cons:

The Names glitch out when the mod is turned off. The normal survivors have the Creatures names.

No custom sound done.

Conclusion:

Try and strip the sound from some from the videos? Once you fix the one glitch I found, and add sound, you shall earn your 10/10.

Pros:

Animations are golden.
Skins are clean.

Cons:

Uncommon infected?

Conclusion:

What this mod has, is great. A very small mod, so a very small review. Good work.

Pros:

Minecraft
Very nicely made
Atmospheric
I loved the crafting mechanics
Animations on Characters are very well done
Easter Eggs are pure epic!

Cons:

The Snow and Rain are rather annoying.
Multiple unfair  insta-kill spots, such as a charger can pummel you into the lava in the caves.

Ran out of Ammo allot.
The Ghast as a Tank, to me, doesn't feel right.
Same with Enderman as Smoker. I would have loved to see Enderman as Charger, Herobrine as smoker, and Zombie Pigmen as Tank.

Seems too short.

Conclusion:

This is an excellent map, well made, and a great call out to us Minecraft fans. However, the unfair kill spots, and the pour ammo placement holds this map back from a 10/10. Although there are a whooping 5 stages to this map, they all seem ether too short or too easy. However, I am eager to see what else you create, as this map defiantly DESERVES to be in the Top Campaigns list, and deserves a Valve Spotlight, possibly even some custom audio for the map, as valve has done with other custom maps. I can just hear Francis saying "I Hate the Nether!"" Also, the clever ester-eggs are gold. Great map, not perfect, but still, great map!
