Pros:

+ first map especially cool atmosphere
+ unique maps
+ traps

Cons:

- the last map lacked style, i mean real ugly grass and the part with the hole and the cabin couldnt even jump thru windows
- ported parts of other games sometimes felt out of place 

Conclusion:

was cool but i think its also 75% done like the l4d1 version of this

Pros:

+ xcellent ending to the series ( aldoug they still roam space for an eternity but theyll probably not be bothered by squidwards house && da whole survivorship situation got a whole lot outta hand ) 
+ inherent to the series: great and unique mechanismz; economical on disk and download space 
+ this episode was especially hardcore with special regarz to the 1st map: ( I mean cmon 2 tanks in dat confined space ; hate to admit we switched to advanced for that part )

Cons:

- not being in the appropriate spots during map 2 with the levels would give you deaht penalty that felt harsh ( like being way too the side not in the middle ) and the sync werent 2 smüth also on that part 

Conclusion:

love it by the balls and if we didnt cheat by difficulty changing it would have taken us probably also as long as space jockeys 1

Pros:

+ p0rtal 2 style dawg robo helper who also turns on yallz
+ another great set of nevrar before seen bosses
+ we felt underwealmed that we got to the excape vehicle after such relatively easy events but then bam, 'nother baus (squidwards house which got a upgrade)

Cons:

- ability to run back after the first time jockey robot screw over makes it significantly easier
- right after u go out of the survivor awake after cryo room, in the hallway u can look out the window and if u look back u see part of the interior of the cryo room --> the space ship had no exterior so that was p odd
- also the floor sound effects didnt seem realistic because it sounded like the floor was so light that by walkin u were making dents in it and dat aint a real feelin of security against the vacuum of space

Conclusion:

excellent part of an excellent series

Pros:

+ bananas
+ barrel
+ donkey kong 
= HILARIOUS

Cons:

- ya indeed some fitting sounds would be great
- tank music also but thats fine because i already got that modded to genki (saints row)

Conclusion:

with sounds as icing on the cake I would definitely Nominate this 

Pros:

+ $$$$$$$$$$$ (dat mean dat the campane is very RICH)
+ i mean rich of character
+ rich of details
+ rich of variety like pathways u can pick and like first ur in a prison and then not anymore and a boat and a very rustic graveyard for i guess real rich people who love da sea but are ok with that their dead bodies might fell in the sea ( becoz of erosion )
+ unique ending 
+ GET 2 DA BAOT
+ many tanks  during champagne
+ many tanks for making campaign
+ music was verging on epic

Cons:

- dat de prisoners had some kind of casual day (no cool saints row prison jump suits)
- in da preezon dar be like loads of medical kits and dat aint hardk0re

[EDIT: aka ADDED:]
- my uncle who works at nintendo told me there would be shields and custom weapons and i ain seen none

Conclusion:

first playthroguh we got like 5 hrs but today we done did in 50 minutes  EXPERD HARDCORE REALISM 
well not realism (juice coop) but its always intense when u got a team of swagger yolostarz

music tips:
(first i listened nicki minaj and then jack sparrow by lonely island because of the boat and the campaigne were like epic like michael bolton (alec baldwins son) 's singing part in that song of jack sparrow by lonely island)
oh yeah that reminds me that the music in the campaine was verging on epic

Pros:

+ the reason I love this campaign is because it's really depressing
+ loved dem $ewers becuase there wuz a tank and we shot it through some railing and he didnt know wtf XDLOL tankz r dumm
+ dat car animation in da begin wuz real $moothlike better than i ever seen

Cons:

- i heard de dumm dumm dummmm dumm dumm bayou sound often and idk whatsup but it felt weird 
- idg the part that you release the brake of dat train part cuz there aint no part pulling it (no ac$ual train) and there aint no slope so what makes it move it seems obnoxious w/ $pecials infecteds

Conclusion:

it be well designed and aight and challanging and i love it

Pros:

+ very environment 
+ very finale
+ looks real good
+ could be a valve® original
+ places for deadcharging for in vs thats cool beans

Cons:

- this is really dumb though because they need gas for their car; but theres cars all over the city man and theyre scouting houses all the time just take some keys and a car man
- also the flares, those things burn up real quick so "follow the flares" seems sweet but ill advice
- so many medkits

Conclusion:

a decent and well-designed campaign

Pros:

+ I consider our group pretty MLG in coop campaigns, but this took us 4 hours on Exp3rd so gj this was hardcore
+ press buttans
+ few resources, very hardc0re
+ yo that was a fun ass end that u see moar survivors but it be more funnier if there wuz dialogue or that they did more AKA shoulda capitalise on that or that they did more 2 help one another

Cons:

- not all too aesthetic (lvl desine and sumt1mes the zombies literally spawn in mid air instead of dropping out of a ceiling or something fancy && whatsup w/ lighting in 3rd map L0L)
- the transition from 1 map to another aint too seemless

[[[[[[[[[[[spoil0r]]]]]]]]]]]]]]]]]]]]]]]
- the finale felt fairly underwelming cause i threw dat molly at the laddar and that kinda blocked all action cause i pwnd them bees right there; also short run 2 safety

Conclusion:

yo its like a more hardcore version of questionable ethics only theres a complete lack of atmosphere

Pros:

+ $WEET lvl design looks real nice
+ dem ea$ter eggs
+ loved the workbench mechanic
 + sumt1mes there be like glitches in the map so u jump somwh1re and then u cant get out: its like expert realism dawg some ppl would say this is a con but i take what i get yolo

Cons:

- $hit man like way too much stuff i have never been dis rich during any campane cuz at 1 point i be like carrying m60 w/ laz0r & explosivz not even in finale, all team was 90+ hps and fully stocked on meds and kits. this was at over 60% of map 2 and it wuz on Xperd reali$m i thought i was playing baby mode

Conclusion:

yo if ur real high or aint so good at this game this is ur lay up to expert but if u like 2 play l4d like ur watching painings and so (and somet1mes kill $ome bees) then this be worth like 10/10 cuz of designz
