Pros:

Awesome layout and design
Finally a survival map with an ending!!!
LoTR Music
Only map I've ever had a screenshot of me taken in (I met Gandalf!!!!!!!)
Return playability - very replayable
Amazingly difficult but that's what made it so much fun - the replay value!!!

Cons:

I want another one!!!

Conclusion:

Friends an me probably put 40 hours plus into playing this map to completion and then replaying to ensure it wasn't a fluke!! :))

Those 40 hours are probably a fraction of the time the author spent creating this!! Great job mate!

If you haven't played this yet, play it now!! A must ....... make sure you got a good team to play with though!!
