The player progresses through the game by finding items and clues which, when used in the appropriate locations, allow access to new areas. The key difference to Resident Evil is that Galerians does not employ gun-based combat, but instead features the use of psychic powers, which make it difficult to fight more than one enemy at a time.
In this game, players advance by discovering items and clues that unlock new areas when placed in specific locations. Unlike Resident Evil, which relies on guns, Galerians employs psychic abilities, limiting the player's ability to fight multiple enemies simultaneously.
