Played this campaign & finished in about 30 minutes. In overalls, the campaign is playable to the finale. Bot navigation is good in overalls, with only the usual bug about the bots not picking up some supplies, like for example, they don't pick medkits in the beginning of map 1 although players push them near the medkits. . Many areas have empty rooms despite being wide. Somehow most maps lack weapon supplies. In my play, I only found tier 1 weapons at most areas & only found some magnum pistols. I got rifle & autoshotgun just near the end of campaign, on the finale. I found no sniper at all. . The finale is confusing a little, because there's no info about where the rescue unit will appear. After the 2nd wave of tank ends, there plays the rescue music, & nothing comes until the 3rd tank with horde appears. Then, the rescue unit only appears slowly, at the same time the 4th tank comes. The longer time to defend on the finale makes it more difficult than the normal holdout finale. The area is wide enough to shoot & run though, & the vomitjar is your best friend, the more vomitjars, the better. . In short, this campaign is playable in both Singleplayer & Multiplayer, but the finale would be difficult enough to play in Singleplayer & require some strategies with a vomitjar.

OK despite not initially finding the game in Add Ons (I was looking for the title "At the Gloaming" not a Hanzi Character set) I got to play. I did this on Solo with Bots. Bot navigation throughout the campaign is generally good (2-3 instances of not picking up first aid or following). Map #1 Zoey and Louis would not take First Aid kits to start. Non of the Bots would enter the building with the large hole. I went inside as I saw a few supply items. Scenery is weird to say the least. Objects are randomly placed. Examples are the building exterior with obvious drywall. Large boats in both small ponds. Docks? Dissimilar walls materials strung together. Shortly after you start it was Tank, spitter, 3 Jockeys and 4 hunters (makes it difficult when you only have a pistol and shotgun). The area inside the building where the lift gate states "Be ready for the Hordes" was weird. I went 1/2 down the long passage before the hordes came. They came as a chase group instead of the usual and expected head on attack. Note this passage also had waving tree branches sticking out of the wall. The witch I blasted but her crazy music didn't stop. <G> Map #2 Starts with a horde at the safe room door (a few minutes to slaughter them). Bots now pick up items including first aid. Again with the strange landscape (resembled a junk yard). No other issues noted. Map #3 Crashed to desktop. I restarted game from Map #3 and it loaded. However the map was directly from "Cursed City" Only a single pistol on the restart. First aid is outside and away from the safe room. Map #4 was also a direct copy from the "Cursed City Campaign". See https://www.gamemaps.com/details/3921 https://steamcommunity.com/sharedfiles/filedetails/?id=853148493 I only rated it with one star as the scenery was just random pieces dropped haphazardly. The main reason for one star was I recognized that I had played the last two maps a long time ago in the Cursed City campaign from 2017. So I knew exactly where to go for these two maps. Person who made those should get the credit (even if it is listed as abandoned).
