Players speculate that the protagonist of Gloomwood may be named 'Jekyll' following the recent Research update. This update introduces a new laboratory setting where players can synthesize a cure for a plague and conduct ethically ambiguous research to create serums that allow transformation into monstrous forms. These serums enable players to blend in with hostile creatures for stealth advantages. The update expands gameplay possibilities, moving away from the initial concept of a 'Thief with guns' towards abilities reminiscent of those in Dishonored, though the abilities are one-time-use rather than permanent. The doctor's journal has been enhanced with new artwork, soundscapes, and animations. Players will access the research mechanics upon reaching the game's mirror realm, with future updates expected to roll out in the summer months.
