Pros:

Very Challenging
Lots Of Surprising Stuff
More Custom content
i liked the buttons if you hit the wrong one you fall
and the twirl thing lol the tank got spun around and was easy to kill.
-SUPRISE WITCHES

Cons:

You die to easy even on Normal
To many Tanks in tough places
Chapters are way to long to survive with little supplies
bots dont help you
bots walk into the traps all the time
bots get stuck
very hard to find weapons and health packs
just pistols on the first part?
no health at beginning
pills?

Conclusion:

This is a good camoiagn that needs alot of fixing and attension. the game even says "this map is unplayable". this person needs to fix glitches and make it a little easier just to get through the maps it doesnt have to be absolutly impossible to get through. and make the chapters shorter one would have taken hours and not many people play Add-On Campaigns so it's hard to get 4 People. Over all i love this map because its very hard to beat by yourself. Expert forget it with the Campaign id give this Campaign 3.5 Stars
