Just finished Zygote, watched Firebase just before that. Holy fucking shit these are my favorites. All of them. I think I like Zygote the best just because of my love of The Thing as well as horror in general but Firebase was just as freaky at times without the classic horror elements that Zygote has slathered all over it. But they're all fantastic and I cannot get enough. I feel like I'm watching a new version of Black Mirror except instead of social/political commentary with technology, it's science fiction/horror. Truly amazing and I'd love to see a series on these. At first I was thinking they were great for concepts for movies but after watching those back to back, I'd much prefer a series with only slightly longer episodes. That would be so friggin' awesome.
Zygote totally had those Dead Space vibes...but better.
