Pros:

-Tells the survivors' stories from two different perspectives
-Follows the plot line closely
-Epic music (Imagine Dragons)
-Animations and cuts fit the music perfectly
-Perfect for L4D2, considering you can play every map

Cons:

-The speed at which Louis runs to the helicopter is super unrealistic (but who really cares)

Conclusion:

The best, by far, intro addon ever introduced. 10/10

Pros:

- Melee on backs of L4D1 survivors
- Adds better realism to campaigns
- Good placement in proportion of weapons on back

Cons:

- Can conflict with certain custom head model addons

Conclusion:

Does just what it says.

For those of you who don't know, THIS MOD DOES WORK ONLINE.

No idea why the description says they don't. It works perfectly fine on offical dedicated servers.

Pros:

- Beta survivors (sort of)
- Beta pistols
- Beta weapon animations!
- L4D1 specials

Cons:

- Unnecessary mods included that weren't even in the beta (adrenaline, defib skin, posters, etc.)
- Beta Nick had a cleaner suit
- All official beta skins are released, though only official Beta Rochelle included (the rest are beta-style)

Conclusion:

Decent mod. Some things should be left out.

Pros:

- L4D1 zombies in L4D2!! ~ 4.0
- Correct sizing proportions to L4D2 zombies ~ 1.0
- Zombies distributed well in locations ~ 3.0
- Shading Boxes GONE!! (Except Dead Center for me) ~ 1.5

Cons:

- Only works on locally-hosted servers :( ~ -0.5
- Gore effects can't be used (I don't really mind)

Conclusion:

Excellent overall. This mod provides a L4D1 atmosphere within the L4D2 environment. The zombies in L4D1 have always looked much scarier and realistic in my opinion. The removing of the shading boxes adds to the intense realism of the game. The fact that the population.txt adds to which the zombies spawn where makes it difficult to find a way to use this mod online.

Pros:

- Map provides extremely detailed and interesting play through
- Large amount of diversity in areas keeping the environment interesting
- EXTREMELY-well bot navigation
- Multiple path options designed for other interesting play through
- Unique types of crescendo events
- The room full of bloody gnomes... O__O

Cons:

- Maybe too many item spawns? If that is even a con.

Conclusion:

This is by far the best, most fun and interesting campaign I've played in my life. The San Fran area helps due to living in the Bay Area, but I was actually able to focus on the environment more than the zombies, which is a very hard thing to achieve in L4D. The item spawns seemed a bit excessive for competitive play, but the surroundings allowed my team and I to take it slow, and the items became worth our time. Overall, this is freakin' AMAZING. Thank you so much for investing so much time & effort into this. It was totally worth it.

Pros:

- Gigantic, well spread out  map with nice scenery
- Cozy, well-lit environment makes navigation easy and simple
- Many unique and interesting places to hold out
- Very fun map to play with friends!

Cons:

- Weapon spawn locations are very few
- Anti-glitch goo appears 3rd floor & up (unless you allow the zombies to follow you up right behind you)
- Bots seem to like to get themselves stuck in the Christmas tree

Conclusion:

An absolutely amazing map overall, especially great for online play with friends. Spread out the weapons on the map (& possibly open the doors so we may explore outside the lodge? :))
