Cool DOOM ARG series called Exploring Lost Wads
Exploring Lost Wads is this ongoing series I've been watching for a while now, it's a series about this dude who's GZDoom (fan-made modern port for classic DOOM and its mods) became haunted by an AI that causes strange occurrences at times while playing, sometimes displaying weird text on screen, changing a random texture or spawning a fully black figure that stalks the player before disappearing in a split second.
The series I believe may be partially inspired by the INTERLOPER ARG by Anomidae by that it has become more interesting over time rather than scary. This series is criminally underrated and I strongly advise to set aside some time and watch everything the channel has to offer as the story goes on.
