Pros:

Fantastic lighting and graphics
Great use of open spaces
Lots of detail and multiple environments
Good length maps

Cons:

Could use a few more ammo piles and health kits.  
Needs a few more arrows to direct through mazes.  

Conclusion:

This is one of my favorite campaigns.  Please don't ever let people talk you into closing the open spaces.  It is perfect just the way it is.  Great Job and Great Campaign.

Pros:

The new sounds work great and really enhance the play experience.

Cons:

I can't tell a difference in the sounds of the M60 or the Ak47.  

Conclusion:

New sounds are great.  I love them and recommend that everyone have them.
