Though it's just a campaign with 4 maps in it, this campaign is kind of long. There are some traps, but fortunately they're not instant-kill traps. The real challenges exist on map 2 & map 3. On map 2, it's kind of really difficult if you play with bots, because at the end of map 2, there's scavenge event to collect 10 gascans scattered at very far places one to another while at the same time incoming attack & SI keep coming. Not only that, the next annoying problem is the scavenge area is very wide, so wide that you won't be able to see where to fill up the gascans. I took several minutes to roam around until I finally found the generator. I'll give a clue to make the scavenge a little easier. Look for another gate that's still closed. If you find that one, you'll know what to do later :) . . Next is map 3. Somehow there's a bug on map 3. I don't know if the zombies cause it or not, but sometimes the rolling door doesn't open when the switch is pushed. When that happen, restarting can fix the problem. & the challenge on map 3 is labyrinth garden :D . I'm bad at finding a way through the labyrinth, so when I played map 3, I did my usual strategies, to stick near the wall. It took time, but finally I could reach the end of the labyrinth garden. It's ok to walk around without sticking to the wall, but the chance of getting lost is greater. . The finale has a really wide area to choose for defense during waiting for the rescue time. Really really so wide, that the incoming zombies look so small unless aimed with a sniper. The intervals before the rescue time comes are longer than usual. I forgot how many times I fought tanks, but as far as I remember, it's more than twice like the usual finale in a campaign. I had to defend near the ammo pile to keep picking up the ammo. Defending at the center near the radio is not bad because most supplies are there, but the area at the center is too open & zombies can come from any directions. Well, the only challenge on this finale is the unusually long interval during defense before the rescue time comes. There are so many choices to defend. Even it's possible to run back to the saferoom, I think, but that's very far from the rescue location. . In overalls, this campaign is good. It's better to play this campaign with friends, because some maps are hard to play with bots. There are also some mysteries that I haven't solved yet. There are some locked weapons on map 1 that can only be unlocked by doing something. There are switches, but when I pushed them, nothing happened (but the bots were cheating, as they could pick the weapons so easily). Maybe I'll play again soon, & try to check more thoroughly :) .

A very decent campaign, a very well made map and I highly recommend that you download this mod in case all the left 4 dead 2 campaigns were already played, it would be more fun to play this campaign because they would have so much fun

支持，这张图是AZ的巅峰作品，和以往相比超越的不是一点点。如果能解决下爆ping的问题就更好了。第二关收集油桶 ，和其他地图相比，油桶放置间距更远，且没有提供投掷武器，同时存在爆ping，就很难在持续的特感尸潮中收集全部油桶。考虑一下写实专家难度的玩家。
