@furd It's called Cretaceous Period, it's on this site. It's the same genre, post-apocalypse disaster military story with monsters, but what ended the world was dinosaurs suddenly appearing all over the place on the planet, not mutant mosquitos. Also, there's nothing silly in Cretaceous, it takes itself and it's scenario seriously. We don't really have an answer as to how the dinosaur thing happened, but it's implied some experiments with something like the Large Hadron Collider damaged time in some way, or otherwise had consequences on our reality we don't understand. Again, that's implications, we don't know what caused it, that's the big mystery of the series. Maybe a wizard did it, we'll find out.
Post-apocalypse military disaster is a pretty niche little genre, but it's one I've taken a liking to. There honestly aren't that many stories for it, but it does kind of exist.
