Ultimate RimWorld Melee Killbox [1.5]

Hey guys, in this video I want to share my best killbox design tutorial in RimWorld so far. Killbox is designed for "Melee Only" challenge, but works great in many other scenarios. I play with all the DLCs - Biotech, Ideology, Anomaly and Royalty, but the killbox also works fine without any. No mods.
Killbox works like this: enemies enter a small labyrinth one cell wide, detonate incendiary mines and burn. Those lucky ones who survive this go to my 3 best melee soldiers who finish off the survivors. Stone fences are placed in the labyrinth to slow down enemy pawns and give them more time to burn. The floor is covered with straw as it burns fastest and spreads the fire. The labyrinth is also covered with a roof, which prevents heat from escaping quickly and makes it possible to heat the room up to 1000 degrees.
The only drawback of the design is that it does not work against mechanoids at all. The room with corpses in front of the entrance is optional and simply helps to deal with enemies faster. There is no problem if you don't have the Anomaly DLC.
I took the main idea for killbox from a random video on UA-cam. I don’t remember whose video it was, but I am very grateful to this person. (message me if this was your video lol).
Write what else you can add to improve this killbox.

Thank you. It's shamblers from "Anomaly" DLC.
