A thrilling conclusion that leaves space for more.
I enjoy the way you thoroughly develop each part of the plot here. First you introduce the flying monsters, whose design is pretty uncanny. The animation on them is a little wonky at times, but in other moments it really sells their creepiness. The way the bridge collapses is interesting, showing that the monsters don't need to be unkillable to cause major casualties, and we see this again with the fliers crashing into the choppers. It seems like you really know how to make each creature fit perfectly into its own niche of death-sowing and how to emphasize the designs with movement. The mouthless big guys are also cool, though they don't get much use here. The invisible monster, though, is by far the coolest. The way it sweeps through people before they can even react is terrifying. The moment the guy's arm just falls off while he's standing perfectly encapsulates the way you keep the tension going throughout. You put the characters through a ring of fire, and when they escape just in the nick of time, they're greeted by another danger. All this punctuated by epic background music, it's really exciting.
The visuals of running up the staircase are one of my favorite parts of this. Makes me think of a "stairway to heaven". The kills in this one were really cool again. I especially enjoyed getting to see Boomer fighting melee style and everyone doing what they could to get the Evils off their choppers. The grunt soldiers really put up a fight. The general using that revolver cowboy-style was a cool little moment as well.
The music selection was great in this one, but the sound mixing seemed a bit off, with some lines being hard to hear. This becomes more of an issue when there's no more subtitles like in previous parts.
Overall, a great wrap-up to the episode. Rides the tension out to the end and sets up some more stories, which we see play out in Repercussions.
