Back to Cloud Ocean - Redout 2 

Post 1.3.1 patch, one lap, Boss (R). Nightmare AI, No Assists, No HUD.
This would've been "Cloud Chaos 2", but the tricks in this one are so absurdly difficult that I just couldn't get it done in time. Most everything is the same, one big exception is the "snake" on Libeccio, where I would've jumped over the entire thing while upside down; that skip has been patched out.
This run isn't the prettiest, but I got all the tricks. It is SO much harder than it may look, and this took dozens of attempts.
