Yeah! The animated short was by far one of the darkest and most brutal, and I loved every bit of it. For context, all the SAMs including Firefly are all genetically modified super soldiers that were made to fight the Swarm Disaster. This story is more akin to the likes of Warhammer 40k, or for more regularly known, it is very similar to the Halo series, in which Glamoth are making super soldiers to fight a losing war, and just like in Halo where the Spartans just as easily die, we can see the Knights of the Iron Cavalry also perish pretty tragically, It's such a good story.
