I'm just uploading the raw recording of my SECOND time getting 23 seconds, I had done it before but of course it was when I stopped recording :/ There's also no audio because Outplayed didn't wanna capture it I guess.
I call it the "Snake Glitch" because snake uses a cardboard box to hide, and you're glitching the game into thinking you're invisible but can still move freely
The glitch involves getting caught first, and as soon as you "respawn" you press W (movement key), space bar (your ability, being solid snake), and E (the interact button) all at the same time, which opens the door right away, activates your stealth, and glitches you outside of the box so that you're free to move without being detected (except for a rare chance of a camera spotting you anyway, it's like 1 in 100). It took me about 2 hours for this second attempt, you can tell I was tired when I was just saying random stuff at the end
My Glitchless PB is about 58 seconds but I'll rerecord that another day.
I hope someone else can beat my record!
