Pros:

None

A must get mod.

Pros:

Minecraft!
Awesome Presentation/Atmosphere
Interesting Special Infected ;)
The texture is just pure awesomeness
Good Gameplay
Famous MC youtubers (yogscast, antvenom etc) are dead

Cons:

None for now

Conclusion:

Just get it already

Pros:

Great Effort 
Pretty good map design
So many @$#%! horde event xD
Real Challenge of conserving ammo
writings on wall might help explain this story xD

Cons:

Not to exciting
Very dull, more lights, more object
Did not really present the atmosphere well (doesnt look like mliltary base) 

Conclusion:

Its good, worth downloading it, but I think it can be improved more. Military base looks more like an abandoned mineshaft :P 

Pros:

CoD Zombie Memories :) except its more chaotic and more weapon  and more zombies!
Random Box is awesome!
General Atmosphere is perfect

Cons:

Fixing  Barricade is kinda hard cause you need to be at an angle to fix it
Tank spawn a bit too harsh :p
Bigger Infected had problems getting in (which i like xD)

Conclusion:

Maybe set tier one weapon on wall and put more tier 2 guns in the box, make stuff more interesting ;)
