Dementium II HD is a horror-themed shooter and adventure game developed by Memetic Games, released for PC in 2013 as an enhanced remake of a well-regarded handheld title. Players take on the role of William Redmoor, a patient at the Bright Dawn Treatment Center whose fragmented memories and disturbing visions form the backbone of a twisted narrative. The goal is to piece together Redmoor's story and escape the facility while a menacing figure known as the dark doctor observes. Combat requires varied strategies across different enemy types, and weapons serve a dual purpose — dispatching threats and unlocking new areas. The game balances action, story, and puzzle elements throughout, with additional encounters involving ghostly creatures in a location called Pelf Village. Compared to the original handheld release, this HD version features updated visuals, improved lighting, and refined controls, alongside Steam achievements, cloud saves, and controller support.
