The animation collapses halfway through, turning a visceral alien horror into a Saturday morning power fantasy. You either accept that trade-off and ride it out, or you bail. The ones who stay get bug-versus-human carnage that swings between genuinely stomach-turning and absurdly fun, crews fracturing over political agendas while cockroaches evolve faster than anyone predicted, and superpowers that feel like they actually cost something when they're used. It's messy. It knows it's messy. That's the point.

Humanity's mission to Mars has become a nightmare. The Annex I crew keeps fighting for survival against the Terraformars, huge humanoid cockroaches descended from insects sent to the red planet centuries earlier. The team's crew members carry the DNA of various Earth creatures to help them fight. The cure for the deadly Alien Engine Virus ravaging Earth remains out of reach, and the crew has learned that some squadrons are serving the goals of their own nations. Now the squadrons must battle the Terraformars and one another in a struggle for global supremacy. Expect sci-fi horror and action as survival turns into a contest between rival powers.
