The Russians built the Starcourt mall and were broadcasting this janky message that Henderson picked up and Robin cracked because she's like, a whizz at languages, and then we got that Erica kid to crawl into the normally guarded elevator when the gun-toting guards weren't there. When we got in the whole thing dropped and we were in a super secret Russian base where they were blasting their way into the Upside-Down.

And I won a fight in there somewhere.
