In paranoia pot-boiler Gangstalk you are the person chasing you

rockpapershotgun.com:

Gangstalk is a cat-and-mouse game in which you play both cat and mouse. It's a stalking game in which you are the person stalking you and also, you are the person being stalked. By you. Yes, I too am wearing an expression of puppy-eyed dismay and confusion. But it sounds interesting, sufficiently interesting that I can disregard the very loud DYSTOPIAN WORLD framing in the trailer.

Devised by Kitten Burst developer Jam2go, Gangstalk is the tale of Cam, an urban explorer in a high-vis jacket with an emoji for a face. He's being hounded by the evil megacorp PANDO, who appear to specialise in the manufacture of digital ghosts. Or at least, he thinks he is. According to Wikipedia, gangstalking refers to "a set of persecutory beliefs in which those affected believe they are being followed, stalked, and harassed by a large number of people." So it's possible that all this is happening in Cam's poor befuddled noggin.

As the game begins, Cam has infiltrated a secret PANDO company town, Kudzu Vale, which reminds me of The Blackout Club's ghoulish chunk of suburbia. There are hauntingly empty carparks, hauntingly empty shopping markets, and haunting pieces of high-concept scenery, like piles of smouldering TVs or gaggles of marionettes who definitely won't move when you look away. Active threats include predatory phantasms called Datamoshers, who look like Slender Men made of VHS crackly bits. But the intriguing part, again, is the whole "you are your own stalker" conceit.

In lieu of a generic camera system you will watch Cam "through the fragmented perspectives of CCTV Cameras, Devices, Agents, and the enigmatic Datamoshers". Sometimes, you're peeking through a CCTV camera in the corner, with the view rotating jerkily to follow him/you across the room. Sometimes, you're the horror chasing him/yourself, wobbling along as he/you disappear around corners, whereupon you'll presumably have to wait for yourself to catch up in order to keep... escaping from yourself.
