If you manage to kill all the people in the first room before entering it, the timer won't start as shown here : I'm assuming this has been discovered before but as far as i'm aware, it never got mentionned.

My question is : Would this be considered as a valid speedrun strat ? If so, then the WR could go down to sub 2sec

Edit : If you go fast enough on the last part, you can also skip the timer from triggering which result to a 0.00 sec final time

We already knew of this glitch, and no, it's not a valid strat.
