Rudy, a fifteen-year-old orphan, discovers he has the ability to use powerful forbidden weapons called ARMs, forcing him out of his home village. Jack, a treasure hunter, seeks an ancient device to deal with his troubled past. Cecilia, a young princess studying magic at an abbey, is contacted by a mysterious voice on her seventeenth birthday, telling her she can serve as a medium between the worlds of humans and spirits. The paths of these three heroes converge, and they team up to embark on a journey to understand their roles in a grand scheme that spans over a thousand years into the past.
Wild Arms is a Japanese-style role-playing game set in Filgaia, a fictional world with elements of the American Old West and medieval fantasy. The game's prologue consists of three chapters, each dedicated to one of its main characters; afterwards, the player controls them as a party. Like most RPGs, the game features turn-based battles against randomly appearing enemies and bosses. Characters possess unique abilities - ARMs for Rudy, sword techniques for Jack, and magic for Cecilia. Characters can also equip special accessories (runes), which conjure powerful creatures known as the Guardians during battles, to attack enemies or assist the party by casting supportive spells.
The game has a stronger inclination towards puzzle-solving than most other RPGs. Each of the three playable characters possesses a set of non-combat abilities called "Tools"; for example, Rudy starts with an ability to blow up obstacles, Jack can send his talking mouse Hanpan to manipulate objects out of his reach, and Cecilia can rewind time to ensure another attempt at solving a puzzle. The game's dungeons contain puzzles, many of which must be solved by using these abilities. During the course of the game, the three heroes will gradually learn additional Tools.
Various mini-games are also available. Characters and backgrounds in the game are done with 2D graphics during exploration; conversely, battles utilize a fully 3D environment with cinematic camera angles.
Wild Arms was released on December 20, 1996, for the Playstation console.
