I'm interested in running AWAN and I was wondering if the "Speedrunning tips and tricks" guides from Alan Wake were any good? What's different for optimal movement in this game that's different from AW? How many tricks carry over?

Not an Alan Wake runner. I can say that length of time you can sprint and time taken to fully regen stamina are modified. AWAN allows you to sprint for far longer than vanilla. Also, you gain back all stamina very fast, perhaps even around 3-5 secs. It seemed like you had to jump about 7 times in vanilla before stamina was fully recharged.
