Pros:

+ epic 
+ layout and music - ilove it
+ map is absolutely awesome, superfun and very challenging
+ i like the idea with blocking armory, fighting upstairs at the door to tower with tanks in close combat when ammo and supplies runs out is fu@%*! tight but ubercool, looking back and all the time and thinking: WHEN THIS GODDAMN DOOR WILL OPEN ??!! ;)
+ teleporting dead teammates
+ running outside the castle with chainsaw in the finale  is still my fvourite part:)

Cons:

- probably not a con but i liked the old finale more, when you fight infected waiting for Gandalf to appear and THEN you win. now when Gandalf is at the start you dont feel the epicness of the battle like it was before:) 

Conclusion:

Its hard and it should be! Thats why its so cool:) No doubt BEST MAP EVER. Period. Hope you make it even better with further releases. Full 10 from me. Cheers!
