Nightmare features much of the same storyline as the original game, with AMS agent Thomas Rogan investigating the Curien Mansion for disappearances of DBR Corporation research staff, including his fiancée Sophie Richards.
Nightmare deviates from the original 1996 game by being set from a top-down perspective. The player, as Thomas Rogan, must navigate 4 stages. Each stage tasks the player with fighting creatures, rescuing DBR researchers, and ultimately defeating a boss.
Rogan moves through the world on a predefined path; the player can only control his aim, with Rogan firing automatically whenever an enemy or destructible object is in his line of fire (represented by a transparent cone appearing in front of him).
Players can purchase more powerful weapons from a shop.
- G, Rogan's partner from the original game, is noticeably absent.
