Play Deja Vu: A Nightmare Comes True!! Online

Deja Vu: A Nightmare Comes True!! is a detective and mystery adventure game released in 1987 for MS-DOS. It was developed by ICOM Simulations, Inc. and published by Mindscape, Inc. The game presented a first person perspective and was notable for its use of mouse support, a multi window interface, and bitmapped graphics during a period when text based interactive fiction was more common.

The player assumes the role of Theodore "Ace" Harding, a retired boxer working as a private investigator in Chicago during December 1941. The game begins with the character awakening in a toilet stall of a disreputable bar with complete amnesia. Shortly after, the player discovers a dead body upstairs and a gun in their own pocket with three bullets missing, directly implicating them in the crime. The primary objective is to explore various locations, gather evidence, and interact with characters to reconstruct the protagonist's identity and uncover the circumstances of the murder before the amnesia leads to permanent mental deterioration, all while avoiding the police who are seeking them for questioning.

Gameplay involves navigating a detailed environment through a point and click interface, combining inventory management with puzzle solving. Players must examine objects, collect items, and converse with non player characters to gather clues and progress the narrative. The structure is non linear, allowing for exploration of multiple locations in a logical order to piece together the story. Key systems include an inventory system for using found objects on the environment or other characters, and a dialogue system for obtaining information, with the player's choices and discoveries directly influencing the unfolding mystery and eventual resolution.
