Fuck yeah. Few seconds in and I already know I'm in for a ride. Excellent bassline when it first opens. It reminds me a bit of bladerunner's ending credits theme. Not sure if intentional, but this sounds great. I like the weapon foley. Neat riser in the middle, before the train ambiences.
I quite like the storytelling you did here with the tune. It has a very cinematic quality to it.
Great work!
