Pros:

>Puzzles (CH 2)
>Small hints given to puzzles (CH 2)
>Constantly challenging
>Large worlds
>Plenty of supplies
>Plenty of surprises
>Amusing additions
>Elevator move-and-shoot style
>Fun finale
>The pilot actually shows himself! Video, and voice!

Cons:

>Bots can sometimes be idiotic (can't pick up medkits/supplies in CH3 saferoom)
>Ladders in CH 2 are extremely buggy, as the bots are constantly being incapped and I'm being bounced around the large hole.

Conclusion:

The map is wonderful and time consuming. Play only if you have a large amount of time on your hands, because these are very large maps. It's better to play with friends, because bots can be smart but they'll, most of the time, not pick up items in less-obvious spots like under the sink and behind crates in small rooms. It is highly recommended NOT to play on EXPERT, because it's not possible :P This is one of the best maps I've played. Maps like these are often criticized negatively, but this one is well made, so I commend you "GARBAGE BOY." :P The surprises are overwhelmingly fun, so people who read this should most definitely play this map.

Pros:

-Great models
-Smooth animations
-Models work in multiplayer (non-valve servers)
-New lobby icons
-New singleplayer Icon
-Exceptional design
-Awesome helmets
-Weapons positioned nicely on the back of the armor, not sloppily done

Cons:

-Items can sometimes go "in" the suit, such as the medpack
-First-person hands view doesn't work (or just me?)
-No media shown, definitely deserves one.

Conclusion:

I honestly LOVE these skins. I always try to find non-Valve servers JUST to see these skins, because they give a different feel of the game. You can easily tell that these skins weren't made in a day or so, as they have amazing detail on them. The animations are incredibly smooth and moves with the model, which really shocked me since they seem to have so much additions to the skin. The only downsides are the medpacks "seeping" into the armor, which kind of bothers me. First-person hands view doesn't work either, so it'd be kind of weird to see skin when your in a full black armored suit from third person. 

Overall, this definitely deserves a very high score ^^
