The gameplay you saw was from "Overdose" staring Margaret Qualley as the protagonist. It was originally a horror game for Google Stadia but it got cancelled once Stadia shutdown. OD seems to be a rebooted version of that with a heavy inspiration from PT, legally it can't be Overdose because Google holds the rights to that game. This version seems to have a bigger scale considering the creative team behind it and the blending of games and cinema.
Ohhh ok thanks, I was so confused. I'm glad OD is something different. The leaked Overdose gameplay looked like it wouldn't be my thing. Also, PT is one of my favorite games ever, so the closer we can get to having that back, the better.
