Pros:

(These are for both the M4 and the Chrome shotgun)
Very enjoyable to use! Means I actually use the M4 and the Chrome shotguns sometimes :)
Powerful and accurate, but not overpowered!

Cons:

Being the fussy guy I am, I dislike the way that you do not have an perfect number of shells for magazine size. If you were able to add +1 to the total no. of shells (eg. 91 shells total) for this and the chrome shotgun, I would be over the moon. No points deducted though :P

Conclusion:

I installed your tight shotgun mod for both my pump and spas shotguns, and your slugs for my chrome and m4 shotguns. They have made using shotguns much more fun (not to mention tactical - to take the slugs for taking out specials at distance, or the tight spread shells for close quaters?).
Overall, very well done! EXCELLENT!

Pros:

-Interesting.

-Character Outfits - Makes it much more in character.

-Good weapon locations.

Cons:

-Very hard to play using Integrated graphics - my FPS dropped to about 5 at some point during the jungle. No points deducted.

-AI took awhile getting on the chopper at the end.

-Quite Short.

Conclusion:

Overall a very good Campaign!

The Vietnam War Film references were particularly fun. Notice the background loading image says 'the APOCALYPSE is NOW'. The Sniper in the city was a clear reference to Full Metal Jacket - You even managed to make it a women sniper (as the witch may have been the sniper)!

One thing that would make this INSANE would be if the rescue helicopter had the words 'UNITED STATES ARMY' on the side of it and the insignia of the 1st Air Cavalry on the front - and of course Ride Of the Valkyries playing when it arrived =]

Good Work!

Pros:

Fantastic Model
Epic Textures
Animations are Great

Cons:

None

Conclusion:

Great skins, however I have a request. Is it possible to release these as different downloads? Only I love the wooden one, but do not like the chrome one so much. Thanks!
