Comments: Completely forgot I did this run before and saw it on DSDA and figured I would improve it.
I think this is the only nomo I have actually optimized to some degree (600 attempts), though 46 seconds will be my limit.

Getting under 49 seconds kinda comes down to RNG (for me at least) because of the pistol damage to the barrels and then the wallrun to the double secret area.

There are many routing options for this map and there probably exists a faster one than this.
