Near perfect campaign. Fun challenging maps that aren't obscenely difficult and balanced well with plenty of defibs for the chaos at times. I honestly didn't encounter any issues, other than a random crash on the finale, probably my end though. other than bots taking a stupid route on the third last chapter I believe, I jumped off a platform into swamp water, got pounced, and the bots took the long way around. Epic ending as well, definitely recommend, classic L4D style.

After testing the latest version, here is my review. The campaign is challenging from the beginning to the finale. It's recommended to play with players because some challenges are hard for bots, especially at town where survivors have to run through horde & then face horde + tank once. There must be at least two players carrying two vomitjars for this event - one to throw to distract zombies while fighting tank & one is for finale. If played on singleplayer, this is where the vomitjar must be spent or the horde & tank will beat all survivors down. . Pros: - No error on the maps - Bot navigation is fine in overalls - There are some challenges, including tank valley - Hints, instructions & highlights are clear. . Cons: - There are some bot navigation errors till the latest version. Like my previous comments below, the spots are still those three, on map 1 near the table behind the trucks, on the bridge where the endless horde + SI happens, & on finale where the rescue helicopter is located. On map 1, the bots have hard time in jumping over the table to follow the player (the only way to pass is to jump over the table), so the player need to wait for awhile until the stuck bots that can't jump will later teleport to the player by themselves. On the bridge with endless horde + SI, if the player runs fast after throwing bile without looking back, the bots are often left behind as if they walk slower (tested twice & in the first test, one bot somehow was still at the building with supplies near the railway while 3 of us were already several meters ahead. On the 2nd test, I was arrived at the end of railway while the bots were few meters behind so I had to wait while being cautious of any SI). On the finale, bots still have problem climbing the stairs to the roof where the rescue helicopter is landing (I tested twice as well, & the bots still got confused on both tries, unless I waited on the stairs until they came & then walked together to the helicopter). . In overalls, this campaign is lots of fun challenges. The "super witch bride" is also fun. I had no idea why the cars started to flip one to another...until I saw a witch bride kept teleporting to pursue us so I had to run like hell so that I didn't get smashed by the flying cars :D . It's not recommended to play Singleplayer in expert mode though, because the challenges are too hard for bots in expert, but it's ok if all survivors are players :) .
