Pros:

Nice map, I liked the idea
It was very cool to look at, beautiful scenery
Good Spread on ammo and health
Good difficulty balance
Fun to play

Cons:

No Tank/Witch/Panic Event Music 
AI stood and watched me die during the finale

Conclusion:

All in all, it was a very good map. I liked the idea, and you planned it and executed the idea very well. I had fun playing it, despite the finicky AI (most likely my fault, I'll play it with my buddies instead :D) The Tank/Witch/Panic Event wasn't there, but that could have been my fault, I'll test it out later. Overall, I recommend this map, to anyone looking for some good fun. 
85/100
