This campaign is long and challenging, but very fun to play.^^ Crossing the bridge in the chapter 3, refuel the tank in the chapter 4, and defense in the finale is the hard and fun parts. Level design is really good, and there have many supplies in the campaign.^^ It will be more fun to play this campaign with friends.^^

This is easily one of the worst campaigns I have ever played. Everything is ridiculously dark, most of the time, you'd see absolutely nothing outside of your flashlight's cone of light. Bot nav is broken, bots wouldn't even pick up weapons, ammo or items most of the time. The worst thing about this campaign is that the director just won't stop throwing hordes at you, which, to make matters even worse, have their size increased from 30 zombies at a time to 384 (!). SI spawned every two seconds with two at a time. I played this in single player mode with bots on Advanced difficulty and killed 7,648 zombies during my playthrough. Not recommended.

Perfect campaign, lengthy 6 chapter campaign with all the stuff included to make this a fun Left 4 Dead zombie killin' experience! Can't recommend enough!

Es larga divertida y estresante en algunos sectores, pero es genial, recuerdo haber jugado la primera version con los otros supervivientes... Seria bueno una mejora en algunos aspectos y reducir un poco la dificultad del puente con hordas infinitas que salen del refugio... saludos

well map design, but too much artifitial difficulty, and npc die over and over again jumpin on the train
