The Bellows is a free horror experience that has been available on the HTC Vive since September of last year. (Also playable on Oculus Rift's with 3 sensor setup) A new trailer was just released, announcing that the game is coming to PlayStation VR. We don't know if this will be a free experience like it is currently on Steam, or could there be a cost to get this relatively short experience? Castle Steps, the developer of the game, had started out charging a price for the game on Steam, before later making it a free experience.
Castle Steps has previously said that the free Steam version of the game might not stay free forever, but that anybody that downloads the free version will always have the experience for free. They seemed to insinuate that there is a possibility that this game could have a price attached to it at some point in the future. It's not completely out of the realm of possibility that the PlayStation VR version will have a price, and that the Steam version will be updated to include a price as well. Either way, you can check out the new trailer that was just released for the PSVR version below:
