Just spent 8 hours on this - this version has temporary textures and coloration, as well as weapon placements and objective spawns. Rudimentary intro/outro shots included.
Geometry is 95% complete, will be updating continually.
Art is... well, a bit of a mess, really. Atmosphere is essentially correct, but need to fix coloration and textures for better visibility.
Inspired by the likes of Construct, Citadel, and the H2 forerunner aesthetic in general, this map may be more ideally suited to Classic game modes - while sprinting is useful, it does not fit the tone (but hey, haven't play tested it so w/e).
I will be tweaking it here and there over the next week.
