Hotline Miami 2 on Hard: "Into The Pit" S Rank
Scene 10. I originally finished this with Tony because I couldn't find a path to keep a combo going in the first (10x) and third part. You just got to be pretty fast for the first part as Corey. The third part required random shooting once you started moving, so Tony was out of the picture (he uses only fists).
I'm sure you can easily get a full combo in the third room. I was a tad bit slow towards the end, but I blew away the originally score I got so I'm happy.
