Jeff Lemire takes the atmosphere of Alien and puts it into the world of these kids trying to survive against both machine and humans.

That's what the story boils down to. Survival and taking care of one another. Similar themes and story beats from Descender, but that's okay, because that series was amazing. Lemire gets to tell a twisted story of redemption and courage while also dealing with loss. On top of that the art is solid as can be and really captures the atmosphere. The ending is slightly abrupt but the rest is great.
