Breath of Fire: Dragon Quarter, known in Japan as , is a PlayStation 2 game originally released on November 14, 2002. It is the fifth role-playing game (RPG) in the Breath of Fire series. Gameplay Breath of Fire: Dragon Quarter is a role-playing video game that deviates drastically from previous games in the series, and is the first using fully three-dimensional graphics for characters and environments. Players control their characters from a third-person perspective as they navigate a number of environments including dungeons and towns where they may interact with non-player characters. While previous Breath of Fire games took place in fantasy environments containing open areas, Dragon Quarter features a science fiction motif that sets the game in a series of bunkers 1000m below the surface in an industrialized, post-apocalyptic environment. Players must travel upward through a network of tunnels while battling enemies and collecting keys. A map system alerts players to nearby doors, treasures, and enemies. Rather than experiencing the entire game in a single play-through, Dragon Quarter is designed to be played through multiple times to experience the whole story. Using the Scenario Overlay (SOL) System, specific plot points and game areas are only accessible if the player's D-Ratio number is high enough. Players' D-Ratio is initially 1/8192 and can only be raised by restarting the game and using the SOL: Restore function, which allows the player to begin a new game while carrying over all accumulated items, equipment, and skills previously acquired. Progress is saved to the PlayStation 2 memory card using limited save tokens found during gameplay. Players may suspend their game as many times as they wish by creating a temporary save at certain areas in the game, which is deleted as soon as it is loaded. At a certain point in the game, the player can use dragon abilities and a D-Counter appears on screen. When the D-Counter reaches 100 percent, the game ends and the player is sent back to their last permanent save. The meter raises continually as the player uses the abilities and can only be lowered by restarting using SOL: Restore. Battles use the Positive Encounter and Tactics System (PETS), described by Capcom as a "combined real-time and turn-based combat". A battle begins when a character encounters an on-screen enemy, and the player can employ a pre-emptive strike. Combat can be avoided by setting traps or leaving food. In combat
