This map takes me back to seeing ctf_convoy in TF2's early life, and I'm certain was Helltrain's inspiration. The time and effort put into this must be astronomical; I saw that "mapping all day makes Jack a dull boy" Easter egg. Plenty of details are here I enjoy that also help balance CTF.
The spawn portals help keep flag room control, a timer exists to prevent endless rounds, and there are jump pads for mobility in middle. I like that Halloween helps justify the outlandish ideas too.
Aesthetically, I love the atmosphere and technical prowess displayed with the dynamic 3D skybox and soundscapes. There's lots to unpack here with creativity and ambition, it's no wonder I bought a map stamp because I want to support people coming up with creative and innovative ideas.
