Pros:

Before anyone reads the actual review, this is going off my own and personal opinion. Which may change as more levels come out, along with bug fixes, and so on.

-Custom Music
-Delivers that Classic RE3 feel back to me, even in 3D
-Custom Brad body model
-1st Nemesis event comes up as the original tank event.
-Custom Textures? I think, I don't believe I've seen them pop up in the actual L4D2 game before.
-Barriers seem to be in correct areas.

Cons:

These are just mainly my nitpicks about the map, so don't pay any attention to this if you don't want to.

-You were never able to access the door on the right when you first entered the Police station, which is very confusing to me in a RE3 remake creation.
-Closing the Police Station gate in the 1st level should be the safe room door rather than adding another barrier behind it with the door on it.
-Ceiling seemed kinda tall in the area after the locker rooms.

Conclusion:

Basically, it's a very nice campaign so far. Detailed the way I would have pictured my favorite Resident Evil to be in 3D.

My ideas would mainly include: 

-More puzzles. (Which the creator said he would get too)
-The 2nd Nemesis battle by the stairwell after proceeding down.
-Removing the door on the right side of the police station, allowing the police station gate to be opened in the 2nd level, blocking off the area where the event was in the first area. Then move the 2nd safe house to the parking garage.
-Make the Police Station gate, to be the safe room doors.

This is a very nice campaign so far, and I hope to see the finale in the factory where you kill Nemesis once and for all. To me, that would be so cool. Next level update I might do some nice revising of my review. :)
