Pros:

-Atmosphere.
-Safehouse music.
-Random paths and events.
-Environments.
-Sacrifice finale.
-Ammo, weapons and items well-placed.
-Details and easter eggs.

Cons:

-Outro could be a bit longer and as cool as the intro.

Conclusion:

Fall in Death is a must-play campaign as all CastorJudo's campaign. 

This campaign wasn't supposed to be a walk in the park at all and this is why I liked it. :D

Pros:

-Interesting HUD Icons
-Killing Floor, b*tches! :D
-Steampunk characters rules!

Cons:

-Low-poly FPS arms, but it's understandable.

Could you convert the other Steampunk characters also? :p

Pros:

Conclusion:

This crap is the real crap! ('Crap' not in the stinking meaning :p) 
A real must-play campaign!
I really liked those new areas and events, I loved the new finale too! 
Football Player Tank and that foam hand melee are really creative... I missed a Cheerleader Witch too! :D

Conclusion:

99/100

Pros:

-Nice map, short and compact, but cool.
-Awesome looking as said before. It really reminds me of an oil rig. :)

Cons:

-Tanks spawn behind the locked door which leads to the escape route, becoming too easy to kill them.

Conclusion:

It would be amazing if you put some zombie workers, even some hazmat guys.
It's a pretty small map, but it's cool as is. 
89/100 :)
