-Nice level design -realistic post-apocalyptic levels -mainly scavenge for supplies -good AI navigation -bots are fine -custom stuff -good panic events -perfect lenght -looks just like one of those official campaings

-too many tanks( 2/3 on chapter 2 and chapter 3) -special infected spawn too close to survivors

Pretty much copy-paste from my review for L4D2 version: „Very enjoyable map layout Length of campaign is just fine - not too short and not too long” „Very cool finale - despite that I personally hate scavenge finales, I really enjoyed playing it especially that it is much better than rest of campaign”

Like wise. „Déjà vu on 1st map - highly resembles No Mercy to me Dumb placement of weapons (shitload of them just before points of no return) and alarmed cars I wonder why horde attacked after leaving train on 2nd level” – actually, now I'm not as I heard police sirens which could cause an horde attack – still, Tank isn't necessary there „ONE weapon pickup in finale (looks like someone forgot that when Tank kills Survivor, weapon also gets punched and flies couple of feet away - good luck with finding it)” – well, L4D1 version doesn't have any „Didn't like ventilation shafts - I was just waiting for Spitter or Charger to f♥♥k me up” – while there wasn't any Spitters or Chargers, I still didn't feel much comfortable in vent shafts, too much „Half-Life'ish” for me
