Beginning Hours: Chapter 1

Short good campaign with a little confusing finale

I played this campaign because I felt like wanting to follow the stories, because, well, I skipped the chapters to "Frozen" & "Neverending War" last time. I never thought that I actually ever played this campaign, but in mashup versions. Only 2 of 3 maps were added to the mashup campaigns. The finale is also familiar, but with different rescue unit. I don't remember the exact names, but they have the word "Beginning" too. Those mashup campaigns are also good to play.
.
Anyway, about this campaign, it's kind of short but playable. Some routes are clear & supplies are enough. Bot navigation has no problem, & the hints are clear, except the finale. I'll explain the finale later.
.
Map 1 takes place at a ship. It's a really short map, because once survivors reach surface, they'll have a holdout event till the rescue unit comes. Helicopter on map 1 is a little tricky. If players just walk to it, they'll be hanging from the ledge as there's a little gap between the ship & the flying helicopter. So, they have to jump to it.
.
Map 2 doesn't have a complicated path, from a factory to an underground place. Somehow there's no special infected in the underground tunnel.
.
The finale is simple but complicated. What makes it complicated is the rescue unit. Everything goes fine, & there are many good places to camp. However, when the rescue time comes after 2nd tank is dead, there's no clue about where the rescue location is, & what the rescue unit is. In my play, I wandered few more minutes with like 2 more additional tanks until I figured out about the rescue unit. It's kind of funny as even nobody would never expect that vehicle was the rescue unit. When players trigger the finale by turning on a generator, there's a pickup truck nearby. Somehow when I ran pass that truck, suddenly I entered credit screen, lol :D . So I found it by luck.
.
So, as the conclusion, this campaign is short but good to play.
