It's been a long wait since the mysterious Ghostwire: Tokyo was FPS game where you shoot ghosts with spiritual energy.
The story is surreal and involves a ghost hunter named KK and the disappearance of the population of Tokyo, but don't take our word for it – you can play the free Ghostwire: Tokyo – Prelude for yourself on Steam or Epic Games Store to get a taste of that story. Not the gameplay, though, as it's a visual novel rather than an FPS.
As the Steam page describes it, this prologue involves "the mysterious KK and his gang of supernatural detectives" investigating an "unusual disappearance, only to stumble upon something even more sinister".

It's quite short, with play times on Steam averaging at just 20-50 minutes, although there are multiple paths to take.
