Pros:

- It has a good atmosphere/environment
- Some unique ideas and events
- It's designed versus in mind
- Good weapon and ammo placing
- Excellent bot navigation
- OST

Cons:

- Transitions between the 2nd and 3rd map is not well designed
- Anti-climatic finale

Conclusion:

It must have been a bunch of work to make this campaign so i'm sad about how the finale is done. Overall I enjoyed all the maps, the only disappointment was this. If you can make it better then I'll raise the score of course. 

Pros:

- Simple but nice design (except some parts - see the cons)
- Good amount of supplies
- Nice fog settings
- Very challenging

Cons:

- The edges of the cliff are too sharp, this could have done better. I mean the shape of it. It's not realistic.
- Why is there a car on a top of a cliff? I didn't saw any roads to it.
- Needs more infected ladder to the cliff. As I saw it the zombies were always climbed up from 2 or 3 spot.

Conclusion:

You should definitely have to continue developing maps. For a first try it's a unique and creative map.

Pros:

- Spain setting
- Well designed and lengthy maps
- Scripted events, like the falling ambulance car in the metro station
- Barca zombies
- Good navigational mesh
- Custom props and textures
- NPCs in the church
- Beautiful outro at the finale

Cons:

- Sometimes it's hard to navigate through the environment, such as on the first map when the survivors have to go through an apartment.
- Lack of conversation between the survivors
- Survivors can't interact with the NPCs
- Never ending hordes at the finale

Conclusion:

In my opinion this campaign is an awesome work from very talented mappers. It's not perfect but none of the cons are significant. I know that the never ending horde was necessary at the finale because the size of the place and for the challenge but still I found it very frustrating when I could barely move in the mass of zombies. Overall I give a 90 out of 100 which I feel is righteous for this campaign.

Pros:

Good atmosphere
Custom models
Well detailed environment
L4D1 survivors
No nav issues
Creative finale

Cons:

Optimization is better in the L4D1 version
Finale was a bit too easy to survive

Conclusion:

This campaign would deserve to be in the game officially by Valve. I would like to play it in versus but it seems no one is playing it. :(

Pros:

- Decent level design
- Good nav mesh
- Well detailed campaign

Cons:

- Easy finale
- Easy to get lost at some places

Conclusion:

I really enjoyed this campaign. It has a nice attention to detail at almost every place. The only problem is the finale, where the survivors can hold out in the safe room. However the other levels were awesome. I'd like to see more maps from you. Keep up the good work!

Pros:

- It has a good atmosphere I'm impressed.
- It's really a valve like map because all of the details and the surrounding environment.
- The best survivor map I know so far.

Cons:

I've noticed a little bug when you go down to the pool. The sound of the water, when you step into it. It hears a knocking sound instead of splash.

Conclusion:

You have managed to create an awesome map. I hope you will continue this as a nice campaign.
ps.: Respect for all the tutorials what you made, and sorry for my bad english.
