Pros:

Fun and addicting!!!
3 heavy machine guns... goody goody
gets hard as hell after 10 minutes...about 3 tanks at once :)

Cons:

if you kill a smoker next to a machine gun hole, you won't see anything.
Tanks swarm the hell out of you after you get 10 minutes...can't run anywhere.

Conclusion:

A really fun map.Great when you have to play survival with your friends,but can't decide.

Heed my advice, download this map.

Pros:

Good remake, follows the original path.

Cons:

The sky looks freaky.
some missing textures and error signs.
if you load the last map in survival mode through the console, you will spawn in a black box :)

Conclusion:

The original Blood Harvest with a twist.
