Pros:

-Great unique idea
-Excellently executed
-Building the barricades is great and fun

Cons:

-Incredibly hard without a friend or someone else to play with
-Small map
-Music gets annoying after awhile

Conclusion:

-As a mapper myself i have little to no idea as to how you accomplished this. Well Done
-I think you should take this idea and make many different small maps with the same barricades and stuff just differently placed giving a change of scenery but still the core idea of barricading and building a rocket

Pros:

-No Mercy l4d1 style (love it)
-Long maps but still 45 min long
-Lots of sidepaths and rooms to search
-Great layout and style

Cons:

-Car that you end with in the 2nd level, the track that it uses should have the settings so that it accelerates slowly rather than full speed instantly (cant remember the name of it)
-Needs more supplies so that its more random when the director selects the items to spawn
-Spinning car in car show gets very glitchy and weird when you stand on it

Conclusion:

-Great campaign, love it, just a couple things to work on like the car at the 2nd level and more items, then this campaign is all set and loaded with awesomesauce. Keep up the good work!

Pros:

-custom speech explained a lot
-map had good details
-i like the idea of going back through the level to get out
-amazing custom tank skin (looked AWESOME)

Cons:

-3 and 4 were very confusing
-3 was annoying where the mobs kept coming and i mean VERY annoying
-fire looked good in some spots but bad in most
-fire on the walls doesnt hurt you and you can go through it
-speech grammers are a little bit off in some places and since you didnt use logic_case to scenes the speech is the exact same every time which gets annoying if you die multiple times

Conclusion:

-very good detail and custom textures are awesome
-the voicing could have used some kind of editing to make it sound like a pilot using a radio rather than a random guy talking and should have been loader because i couldnt hear it all that well over all the shotting and screaming of the zombies
-a very good artic map and i can see why it won

Pros:

-AMAZING visuals
-ran perfectly
-long levels
-feels like episode 1
-finale was fun

Cons:

-speech is a little wierd sounding and big delay between each person talking
-finale music mixes with l4d2 music and sounds like the computer is dieing
-should have used custom hl2 models like the combine soldier replacing the swat guy
-very few swat (i only found 2)
-rain doesnt show up unless the shader detail is set to very high
-quite a bit of witches in the first level (i found 3)

Conclusion:

very good campaign but could use a bit of a hl2 touch with some custom models added and sound fixed but overall a very good campaign i would recommend this to anyone
