Pros:

Nice details
I love the "remodeled" tank
Awesome heart-pounding tank and witches scene
Cool music
Nicely placed supplies

Cons:

Not enough places to explore i.e. ramshackles,cabins,farmhouses etc.
It was a bit difficult to find  my way
Sometiems bots seem unresponsive

Conclusion:

Overall, I liked the campaign. It was a bit hard at some parts but it's really fun to play. 

Pros:

Liked the concept. 
The Manor house map is the main highlight of this Campaign. Really liked it. It was new and different.

The hordes were good. Popped out everywhere.

Health ammos are decent.

Cons:

The forest  parts were confusing! Had to sloow down to make sure I don't get a surprise hit from zombies.

Inside the Manor house, going up to light the torch made me dizzy. A little space each time we ascend would be better.

In the finale:
The area was too small to run around. 
There was no ''defense'' where we could stay. 
Only one building can be ''opened''. 
Supplies wasn't evenly distributed.

Conclusion:

Yeah. You should definitely try this campaign out! Personally think it's easier than the first I Hate Mountains campaign. 

Pros:

OOOH! I LOVED THE RIDE ! IT'S WAS GOOD! :) 
THE MAP WAS WELL DETAILED.

Cons:

IT'S TOO SHORT!! MAKE MOREE!!

THERE WEREN'T MUCH TO GO AROUND TO.IT'S JUST ONE SINGLE PATH. 

Conclusion:

IT WAS TOOO SHORT THOUGH. BUT OVERALL, I WOULD RECOMMEND PLAYING THIS CAMPAIGN. IT'S REALLY GOOD! 
IT WOULD BE AWESOME IF THERE WAS A MAP THAT WAS A MAZE. AND IT WOULD TAKE A LONG TIME TO FINISH IT. JUST A SUGGESTION. 

Pros:

Cool details. 

Cons:

The last part was WEIRD.i mean really weird. The screen changes colors and the BLACK thing?! what is that....

 on the last stage ,The bots were falling down instead of CLIMBING down. gotta fix that

Conclusion:

OVERALL. IT'S A NICE CAMPAIGN. Detailed. I recommend playing this. Although there were minor problems....MUST download

Pros:

Most of it.

Cons:

Why was there no weapons in the barn?? and why did the escape vehicle change? it took me a while to look for it. 

Conclusion:

It's great.It's unique because you changed the escape vehicle.the helipad is awesome.and you should put weapons and timebombs in the barn :) 

Pros:

Exactly the same on the original death abroad. The DEATH ABROAD IS SO FAR MY FAVORITE CUSTOM CAMPAIGN.so remaking it is awesome! the new weapons also makes killing the zombies faster.

Cons:

starting from the 4 to the 5 level zombies disappear after killing them. weird. and tank is also easy to defeat. just a few hits and it dies..WTF?! O.o hehe :)

Conclusion:

I LIKE IT. download it if you want a good custom campaign.

Pros:

New weapons like the grenade launcher makes enemies on the last stage be killed faster. very similar to the original map. I like it.

Cons:

It's quite easy.Not much zombies on where you would be sniping on the rooftop of the church. 

there is a major bug where you have to operate the generator. the evac. door just opened and finished it without touching the generator. O.o

Conclusion:

OVERALL GREAT.MUST DOWNLOAD FOR L4D1 FANS.

Pros:

Very similar to the Original.Almost everything is good.

Cons:

Wished you should've added more pipe bombs and melee weapons.

Conclusion:

Overall ,I'd give this a 99. Very fun and i missed the first left 4 dead campaign ..so yeah.Must download!!
