Resonance of Fate is a role-playing game set in the future when humanity has moved to the machine-city of Basel . The city is built high up in the sky on a tower-like structure. The story follows Vashyron, leader of the PMF, and his companions Zephyr and Leanne as they take on missions from the citizens of Basel. The gameplay involves a unique turn-based system called tri-Attack-Battle (t-A-B) . Players must manage an action gauge to perform actions like movement, charging, and attacks. However, enemies attack in real-time while the player is performing actions. Building up a charge is crucial before attacking, as it affects the type of damage dealt.
Special attacks are called Hero Actions, which allow characters to shoot multiple times while invincible to enemy attacks. These actions cost Bezels and can be replenished by destroying enemies or defeating them entirely. There's also a Tri-Attack special attack that all three characters can perform together, but only under certain conditions.
Combat requires strategic use of the action gauge to deal both non-permanent scratch damage and permanent direct damage. Dealing direct damage also makes scratch damage permanent. The player must carefully manage their characters' actions and Bezels to emerge victorious in battle.
