Sound keeps cutting out because I keep tabbing out and back in.

The only thing that I think might invalidate this run is the last survivor jumping in a locker at the end as I'm getting closer but you can see in the end game screen she had Head On so I think she was just (poorly) trying to do a play with that.

I'm pretty sure the timer starts when you start moving and ends when all hooks stage bars have depleted so this is around 2 minutes and 3 seconds, but I haven't been bothered to calculate the exact time.
