Pros:

- Very detailed enviroments. VERY DETAILED.
- Custom graffiti.
- Lenght of chapters is just fine.
- Well-placed ammo and goodies in all chapters.
- Random and innovating panic events.
- Multiple path choice.
- L4D1 survivors.
- Easter eggs.
- Original finale, with two possible rescue vehicles.

Cons:

- Color correction, wich is good, but can get annoying from time to time since there are so many areas with their own color setting.
- Takes time to load the chapters. Much more than other campaigns.
- Can get a little laggy from time to time. Needs an optimization.
- Certain bugs in the second chapter can get you trapped in trees.
- Water that kills you should be more warned, "THE WATER IS CONTAMINATED AND IT WILL KILL YOU" kinda warning.

Conclusion:

Long, challenging, innovating campaign. Easy a first place in the 2012 releases. You can tell all the effort put in this campaign and it is very fun to play, alone or with friends. While playing with my hommies we couldn't stop singing "Back to School" by Deftones, you should put that song in the credits, LOL.

Pros:

- Very detailed enviroments.
- Nice story.
- Nice chapter length.
- Optional voice acting disabler.
- From bright sunny areas to pitch dark caves and facilities and viceversa.
- Well-placed weapons and goodies.
- Custom music, and well-placed too.

Cons:

- The sand is too bright and sometimes it's annoying.
- Final chapter with no ammo piles.
- Tanks in final chapter can get stuck in the windows of the building where the medkits are.
- Voice acting is a little too loud.
- Could do with more uncommon common infected variety.

Conclusion:

Needs some polishing, but it's very good campaing. The contrast of sunny bright areas and pitch dark caves is a nice feature. Good story. Kinda reminded me some Black Mesa chapters. Can't wait for the final version.

Pros:

+ REALISM.

Cons:

- None.

Conclusion:

This is how it should be. It's perfect. It makes you more aware of your surroundings.

Pros:

- Nice color and details.
- Suits better with the game atmosphere.

Cons:

- Still beta.

- Looks awful with paged pool memory available set in "low". (Setting it in "low" is the only way to play custom campaigns without the "runtime error" crash that closes my game :c)

Any way to solve this? The default icons look nice even with the paged pool memory set in low, so I guess there is a way to do the same thing with this awesome icons. 

Conclusion:

Very artistic. Nice. I'm using it, I recomend it. Can't wait to see the final product.

Pros:

Lots of details.
Cannibal Corpse FTW!
Fallen Model.
Skirt.

Cons:

The sneakers are a little odd, kinda malformed (nice detalis and textures, still).
Maybe a "pants" version of this skin would suit better the metalhead chick concept.

Conclusion:

Nice in overall, but the sneakers are kinda odd.
You should try a pants version, maybe some black jeans and her default "converse" sneakers.
