Pros:

-Mod has more than 7 words as a description!
-Great composition of vistas
-Good use of lighting
-Survivor vocal audio
-Custom weird creepy cool music
-Branched paths and explorable pockets
-Good use of player leading decals (spraypaint arrows, safe house symbols, etc)
-Foreshadowing the boss fight before getting to the boss fight
-Intro helicopter sequence
-New innovative ideas; crafting bombs, vending machines that heal you, picking locked doors
-Contextually appropriate weapons, especially the ones making use of the animated zombies skewered with a sword
-VERY unique overall
-Very unique finale, with caveats
-Small details that most people won't notice, like the jokey in the kiddy ride entering the store and then he's missing from the kiddy ride when you go back outside. Poor evil zombie... =(

Cons:

-Restarted mod and started on map 2, intro safe room was bone dry. No health kits, no tier 1 weapons, nothing
-Deep water with rails around it in Map 1 but had items in the water. Rails around water = "this water is dangerous"
-Rolling crescendo in Map 3 isn't stated to the player
-Map 3 rolling crescendo also had a branched path at the very start. 50/50 chance of going wrong way and ending up at a dead end
-Lockpicking is just opening a door really slowly with no alternate outcomes
-Finale jankiness. Zombies can't jump onto moving brushes (dock section) also if playing with survivor bots they WILL inevitably drown themselves as they derp out trying to stay on the dock

Conclusion:

I play and review a ton of mods, and this was a breath of fresh air in the stale bag of most L4D2 mods. It was hands down the most innovative and most fun L4D2 mod I've (probably) ever played, while still maintaining a high level of detail for construction. The pro's drastically outweigh the cons and I wholeheartedly recommend people play this at least once.

Pros:

Decent lighting (some times)
Good use of directional cues (spray paint arrows, safe house symbols, etc)
Branched paths, not super linear design
Exploration pockets
Good variety of pickups and health items

Cons:

Invisible collision in some areas
Infected jumping onto moving train is janky
Unfocused lighting (some times)
Default lightmaps make for no contrast or interesting shadows
Exploration pockets sometimes had nothing in them
No audio between survivors both ambient conversational stuff or directional leading audio
No landmark guiding me through mod
No context for why I'm in this city, why I'm going to the docks, etc
Finale was waaaaay underwelming, super safe, zombies only have 1 approach, mounted gun and waist high cover protects against chargers/smokers, VERY short run to vehicle once it's finished
Janky trying to start finale with bots. Nav mesh for bots to be "ready" doesn't extend far enough out, have to pull or push survivor bots into it (not an issue if playing with 4 human players)

Conclusion:

Despite the cons outweighing the pro's it's a decently created mod that follows the safe formula of most L4D mods. For that, most people will enjoy it I think. Unfortunately, it doesn't really stand out or do anything innovative so it will likely get lost in the sea of other mods that stick to the same formula.
