Pros:

Better idea than dropping a horde of infected with a single pistol clip.

Adds tension, ammunition COUNTS.

crazy cool gory attacks by zombies.

Cons:

Doesn't really work that well with the way the original game is designed to be played.  Shot to the head doesn't work out perfect when 100 infected are charging in.

Quick Death by flames idea doesn't stack up with dumb AI bots  or probably players either.

Conclusion:

Remember that scene from Dawn of the Dead (either one) where they are surrounded and barely escape?  I don't think the people in those movies would last 30 minutes here.  On some maps even on Easy don't expect to get too far.
You will do ok on maps which have less infected.  

I don't mind running out of ammo at all.  Frankly, I think the game normally gives players too much stuff. 

The zombies move slower, about 50% slower.   Although, the built-in game animations make some of them look like they are contestants for Roller Disco.  

Unfortunately the way that left 4 Dead play is set up, it's not very compatible with super tough zombies.  If nothing else, it makes using mele weapons the only real way to play.

When an entire yard of zombies decides to attack, you will have your hands full.  Oh, and that is probably right before a random horde event too, leaving you with about 70 zombies at point blank range you have to kill by shooting them in the head.  Don't try this on a map with gauntlet!  

Players also take more damage from zombies and MASSIVE DAMAGE from stuff like fire (as-in you will die almost immediately).  When playing with bots, they routinely walk into flames and die right away.  The next bot goes in to help them and they die too.   The fire damage is WAY TOO HIGH.  Yes, it may be realistic but that doesn't make it good game play.  I can see someone losing 50% of their health by entering flames for a moment but to just kill them is a major minus for this mod.  Fix the fire damage and the mod is an 8.

It's a great idea.  Probably the only way it would really work is with fewer zombies than the game/Maps actually dish out, and few bosses thrown in.  As it is, due to the difference in the zombie strength and the way the game provides physical damage you will witness some very strange  sights.  A zombie attacks with half his head blown off, a zombie attacks with no arms, a zombie attacks with out stretched arms with NO HEAD!  

I like the mod.  It's a cooler idea than the original way of dropping a zombie with a two pistols shots.  I think it would work better in some sort of campaign/Mod that was designed to use it (If the designers could reduce the number of Zombies and bosses).   Otherwise, you end up being surrounded.   The fire damage needs to come down. 

 Great work by Ferretsshadow, almost fit a square peg in a round hole.
  

Pros:

Interesting Idea.  Worked ok with AI, even though you had to feed them guns, they didn't seem to really understand how to reload the ammo at times.   Took  a while to win, which was good.

As it stands the map gets a 9.  Not because it is the greatest map design you've ever seen or the highest detailed map.  I give it a 9 because this is the type of idea more people should use.   Having tasks to perform is way better than  your "run of the mill" map.

I'm sure someone else can run with this with a better map design.

Cons:

Building fences does not seem to be particularly useful since most infected go around instead of climbing over them.  Would be better if building the fences gave a solid 80% coverage for them to climb.

Supplies once unlocked should be somewhat limited (if possible).  Even if that means 12 pipes, 12 biles etc.  They shouldn't be unlimited.
 
Grammar errors were no big deal, you could still understand - no minus.  

Conclusion:

A great idea.  Not the best map design in the world but interesting

Pros:

Nice design, huge house with plenty of supplies
Nice storm.

Cons:

Once you move up to the attic level of the house, you automatically win.  The tanks can not enter some of this area and for some strange reason the other bosses do not seem to enter either.  I literally had it going for 20 minutes with AI using pistols until I committed suicide.  No supplies are even needed, just pistols.

Conclusion:

Perhaps the author should cut out the attic, reduce the map size slightly and institute a barricade system into it.   It did have frame stutter, but it is a big area.  Unfortunately, the design is wasted on the fact that the survivors can win indefinitely fighting from a fixed location in the attic even without supplies or real weapons.

Pros:

Has some more involved puzzles.
Darth_Brush stepped up to the plate and finished it -BRAVO
Has somewhat of a story.
Top Notch environment
A Solid 10

Cons:

Given the engine they had to work with to make an interactive game?  I would say none.

Conclusion:

I played this campaign through it's various versions and it's various setbacks, hype and forum fire storms.
I applaud Darth_Brush for actually finishing it.  Perhaps not the way they claimed it would end (with the appearance of a fifth AI character) but it was finished.  

I wish more people making campaigns would take a lead from these guys and incorporate some type of story into their campaigns and some puzzles.  It's not easy to do in Left For Dead but it is certainly a notch up from maps being hooked together with nothing else but hordes of zombies constantly attacking.  A campaign is more effective when you have some motivation, story, goals and less constant hordes.  This is a 10 campaign because they attempted to do that in the limited engine available.

Pros:

Looks great
Tons of stuff
Nice environment

Cons:

unfortunately since the roof was probably one of the best spots to fight, you really lose most of the fact that it is a McDonald's during the fight.

Conclusion:

Good map.  Like I said above most fighting was done on the roof so at the time I might as well have been fighting on a warehouse.  But, I only played it a couple hours, there may be other good spots.

Pros:

Some of these maps, especially Haunted Mansion should not be missed.  HM better than some of the stuff in Dark Carnival.

Cons:

Need the sound fixed.

Conclusion:

Hope the sound issues get worked out.

Pros:

Way cool map.  Gets the feel of the movie, especially outdoors.  I was looking for U-Need-A.  Great attention to detail, the "rabid weasels" were in the crematory.

Cons:

Noticed the clipping at the front gate, no big deal.

Would be cool if police car could actually have textures on it of the Louisville PD (I'll photograph an actual Louisville police car if it would help!).

Would be good if new music track wasn't riding on game music.

Conclusion:

This is one of the coolest single maps out there.  Ernie would be proud of his morgue.  This could be a great full campaign.
