Pros:

Great looking
Survivors look how you would picture them in MC form
The scale of the characters are just right

Cons:

The bodies can get in the way at times

Conclusion:

Overall a brilliant mod apart from the bodies sometimes getting in the way but I'm guessing that is the sort of thing you'd have to expect from a mod that offers this fun, unique and visual element.

Pros:

Works well with the animations
Looks great
A must for People who enjoy Minecraft

Cons:

Can cause you to not take the zombies seriously

Conclusion:

Overall a really great mod that caters to a need if you have a minecraft map. I would advise players to try to remember that the infected are still just as dangerous despite their fun blocky appearance.
