Speaking from Experience

As I see it, it looks okay. Granted this is off of screenshots and not a video. My recommendation, to get a better rating, is to post a showcase of it much like I do, that way people can hear how the songs flow during the finale.

Pros:

-The music was great.
-I found the effects such as the lightning, tornado and the comets ere amusing.
-The help from the old survivors added a sense of dejavu.

Cons:

-Tended to lag a bit but that was because of my laptop.

Conclusion:

Nice "easter egg" at 15 minutes on Survival. ;) The sound effects from the actual game made me laugh.

Pros:

-Really enjoyed the fall, the "eeriness" and the planned events such as "blow up the truck to clear the way" and "fuel then start the car to get past the gate".
-The mines reminded me of the ones from Half Life 2 when fighting the giant worm I believe. (In one of the EP's.)
-The different TYPES of area's each map. (such as the train yard, the forest, the city, the farm, etc.)

Cons:

-Navigation. Massive issue with this on multiple maps. (As in to point where to go)
-The glows for the bombs and the gas can.
-The non-stop horde during the crane event. (as in wave after wave, with no pause in the middle.)

Conclusion:

On a few maps, I ran into the constant (every few minutes) question of "Where do I go now?". Example, on the first map you have 2 ways to go at one part, and one way was back to the very beginning. This happened several times. Another example would be linked to an issue I stated above with the glows. During the last map, to "start" the event, you need to grab the gas can, fill up the car, and start it. This wasn't clear because when playing this map specifically, I ran right by the gas can (I would assume) because I couldn't tell it was a needed item, went up the ladder and sat there for about 10 minutes trying to figure out what to do, then backtracked and THEN it glowed. Another incident such as this is in either the 2nd or Third map with the explosives. It took me a good hour to realize what to do because the glow on the first bomb didn't show up until I had gotten killed, respawned and then ran all the way back. The second glow wasn't too bad, it was near the main area in the hay, very visible.

Overall I had to give it this rating due to the cons. It was an interesting map, cleverly done, I can see you tried to be creative with it. If you want to see my run through of this map and see how "difficult" it is to someone who has never seen it or played it, check out ReapersGaleTeam on Youtube. Otherwise, my rating stands at 8.5 .

Pros:

-Detailed
-Loved the Custom Sounds
-Adding in "Ramoomoo" (aka the Prehistoric Ramirez/Gnome Chompski)
-Custom Propane Tanks/Common

Cons:

-The Finale glitches up something fierce when playing with a bot.
-There's no real indicator of where to go in the finale. (Read Conclusion for more info)
-The Alleyway, if a tank spawns, massive trouble for the bots.
-Subway Event

Conclusion:

I give it a 9/10 because the A.I. needs some major work on both the survivor and infected side. After the event (I believe) there's a fenced off section, not only did a Charger try and attempt to charge through the "wooden barricade" but Nick had issues going around the fence, he was instead attempting to go through it. This is just one of the AI issues I've found though. The other BIG issue I've seen is in the finale, if you're playing with the bots (on Single Player) they seem to glitch hang on the ledge above the button before you even get a chance to get your weapon (M60/Gren.Launcher) or your melee (Chainsaw) and it was an over all annoyance because the horde starts directly after the lift is finished, and you're stuck there helping the bot.

When running the event in the subway, I was unaware there was a gaping massive hole right there, maybe add a bit of a warning for players if they haven't played the level through several times?

I ran into a DIRECTOR issue on this one. You see, in the finale, on my last attempt at TRYING to finish it with bots (and yes I was on Advanced, not Normal/Easy) a random witch spawned as soon as we got off the lift right below the platform, and being the genius Rochelle is she decided to run into the witch and get killed. That's not all. Coach then got stuck in a "ledge hang" on the same spot as I mentioned before, despite the lift had been up. Nick then danced around Coach and got incapped himself, and I wasn't able to get at them because of the constant triple-hits of the special infected (mainly got Spitter/Jockey/Charger).

The last issue I ran into was, as stated above, the CONSTANT triple-hits from the Specials. If it wasn't SpJoCh, it was Smoker Charger Boomer, or Hunter Jockey Spitter. I eventually got through that by considering the "If I hear one infected, there's bound to be 2 behind it." idea. Overall I ENJOYED the map thoroughly but the cons/bugs I found really annoyed me to a rage quit extent (after about 5-6 attempts of the finale on Advanced, but the above cons/bugs are what caused me to quit).
