Not really any spoilers, but if you're gonna play it anytime soon maybe skip this and enjoy the opening yourself.
Otherwise, enjoy this album of pretty Soviet retro-future aesthetics because I'm terrible at playing this game but ok-ish at taking screenshots I think.
Edit: The rest of the album is here. I'm bad at posting apparently.

Those are Sechenov's offices (see the plane screenshot) who is the lead scientist who saved the world and built this flying city complex. His building is just based on the Palace of the Soviets.
There are lots of statues of Lenin though.
