Pros:

(1) Fun Easter Egg Hunting

(2) Enjoyable Custom Intro Music

(3) Cool Tank Skin

(4) Funny Re-skin of a Melee Weapon at the Finale

(5) The Bowling Venue (had fun shooting the bowling balls down the lane, too bad I never struck a single bowling pin down once lol)

Cons:

(1) Survivor Bots refuses to take explosive/incendiary ammo upgrades

(2) 4th Map fairly long to complete in terms of distance, dying at the end of Map 4 when the train leaves due to being smoked after all that hard fighting to get to Crazy Ron makes me sad :( 

(3) Not a major let down, but when I was playing at the part to release the boat, I was really expecting some sort of boat ride down the river cuz of the turret gun, but turns out that it only forms the bridge and by the time the boat arrives, the horde would have been taken care off and the mounted turret on the boat no longer serves any purpose.

Conclusion:

Overall, a fun map indeed, though one suggestion is probably, if there is time, to split the 4th map into 2, or making the 4th map a bit shorter in terms of distance to cover.

Despite a v.3.0 update, the survivor bots still refuse to take any of the ammo upgrades, not a con if on multiplayer but for single player it would make a difference in surviving mobs if the bots actually take the upgrades

All in all, a very fun enjoyable map :) Thumbs Up!

Pros:

1. Excellent challenge after falling back into The Keep
2. True to the LotR story
3. Good use of the L4D1 Survivor bots in the first 7 minutes

Cons:

1. Music could be turned down a little, not too much.
2. Bot navigation still a little buggy in some parts depending on situation (my experience being the part where we're suppose to go deeper into the castle after loosing the gate and always 1 bot will get stuck and won't move anywhere)

Conclusion:

I LOVE THIS SURVIVAL MAP!!! :D

I have read your changelog and I understand that Version 14.0 won't be released until more features are released by Valve, but while most of us wait, my friends and I are quite happy to play with Version 13.0 for now.

My suggestion, though you don't really have to, is if Bill could also somehow help out in someway in the first 7 minutes and during the part we fall back to the keep we see Bill die after attracting the horde to save the players and l4d1 survivors. That would be a fitting heroic role for Bill rather than having him dead at the start of the map. Not sure if it is possible but if it is, it would be awesome. :)

Another suggestion would be to also include Whitaker, the owner of the Gunshop from L4D2 first campaign. Probably the same role as Bill but a bit more minor compared to Bill
Since Valve has released an infected uncommon common that looks like him, could have him lead the Tanks when they start rampaging. :P

Those are my suggestions. Other than that, I salute you for your credit to the L4D1/2 Community for making one of the best, if not the best Custom Survival Maps :)
