Pros:

nice detail in the map,very nice
custom music which gave very eery feelings [ on each special infected]

Cons:

OH GOD THE LAG WAS AWFUL -- very bad lag.
missing images/pink black checkers? errors a lot of then.
the special infected spawns very easily like lets say we could have just killed a hunter but out of nowhere a second two later is a spitter.
what intro?  all my game did was just turn black the screen did and i couldn't move side to side until i saw the same black screen

Conclusion:

The lag is just awful man I didn't even get to continue playing because of how bad it was? Not to mention the errors,and pink/black items? it made it very difficult to play. The details and music were the only things i really liked about the map but in the end i stopped playing all together [didnt even finish it] and deleted. 

Pros:

 nice design,its very different but i think thats what makes it so appealing.

great music ,it gives a very..strange feeling. it suits well.

you need your full concetration on this in order to survive which is fun yet a difficult challenge. 

Cons:

bots are kinda useless. they don't follow,don't get weapons. So its only good if you play with friends.

not much room to fight especially if the round bars are coming down. especially with tanks.

the movement I mean its okay but i guess there should be more then moving up and down? Its really great your map but it kinda gets boring after awhile

Conclusion:

This is very addicting to me I cannot stop playing everytime I die!

I agree with the other reviewer though on how it gets boring after a while. I appreciate the creativity of the map,and the whole design. the music is absolutely wonderful ( I would love to know the songs used! ) and i'd really love to see more from you! I just think the movement could use more work but so far its really good!
