Pros:

- Some places have really good design and lights
- Finale is perfect, creative, spectacular and have a really good gameplay 
- The boat is a cool area, a place we remember. 
- Event in prison. (refectory is believable) 

Cons:

- Start video not that good 
- Flies sound
- Transitions between sounds are too brutal
- In level 2, you don't get immediately that you have to go in the sewers and it's not really dangerous to go in to repair the wire. 
- Level 4 has many problems on textures. Looks pretty bad. i'm sure that some don't have that problem, but it is really annoying. 

Conclusion:

The Finale of this campaign is really really good and fun to play. But besides of design, i'm not 100% convinced that the gameplay of the four first maps is that good. To sum-up, i'll say that  best parts were the jail event and the finale in my opinion. 
Thanks. 

Pros:

- Fake chopper end has humor
- Final is the best part of the campaign but should be launched by players. 
- Nod bad level design 

Cons:

- video at start too long is static shot
- too many tanks
- first event too easy cause the way to the safe house is too short. 
- Finale should be launched by players
- Lightning is not good, there is a lack of atmosphere, light gives some volume to your set, for the moment your good level design is flat. 
- during fake end, chopper should move more during attack
- difficulty balanced during campaign

Conclusion:

- Nice ideas but could be a much more better campaign with more details and lights work. The gameplay experience for the players is not well balanced. Sometimes nothing happens and during the Finale you have to run in the middle of many zombies. I did'nt like first maps, cause of lights, and the level design is too much, corridors, tank, corridors, tank...) The Finale is on the contrary a nice piece of work. 

With few changes, this campaign could be a very good one. 
Good luck and thanks ! 

Pros:

- Neurotoxine is a good idea (but.. look at cons) 
- Ambulance is cool 
- Safe houses are cool. 
- Dialogues
- cutscenes
- Nice slow motion (but..) 
- Good level design 

Cons:

- Light is not always that good. 
- Video start, good idea but not really well done. (camera shakes and crosses elements) 
- Flooded parking is cool but nothing happens. 
- Ambulance guy should end somewhere logical (like in a garage) 
- Should have  an automatic recorded voice in map 3 saying "Sector B under attack" 
- Bad spawn map 4
- Nice slow motion but too long (should keep one shot for slowmotion, one on the chopper  and one for the result of the rocket) 
- Some small parts of the campaign seems unfinished (the finale). 

  NEUROTOXINE : 
- Neurotoxine should be more understandable and logical in the world of your campaign : 
several propositions : 
1) coloured fog (green, purple, orange) to be visually toxic. 
2) Signs with "military uses neurotoxine, danger of death"; "Poison"; "Toxic"
3) Written in capital letters on walls before tunnels : "Neurotoxine doesn''t kill zombies, just us" - "Don't go in there : Neurotoxine and zombies !"
4) reaction on the player (coughs, "get out of that shit !", effects on the screen) 

Conclusion:

This campaign has a lot of good ideas but needs to get some changes. 
Neurotoxine needs to have some custom stuffs to be believable and understandable. 
Your map definitely tells some stories and this is very cool, it's quite fun to play too even if during first tests you die several times cause you dont understand what is going on. You can die but you have to understand why you died in the world you're telling. 

In my opinion, those are the problems you need to solve to offer a great campaign. 
I hope you will continue to work on this. 

Thank you.
