Your music is under attack, you must liberate it!
Symphony is one of the most music-driven games ever made. In this vertical shooter, re-experience each of your songs as it becomes a unique battlefield driven by intensity and tempo.
Your music collection is now an item collection! Each of your songs contains an item you can discover, equip and upgrade. Fully customize your ship to reach score targets, upgrade items and unlock new difficulty levels.
Showcase your skill. Symphony's innovative per-song leaderboard rewards you more, when you dominate with less powerful weapons. Find the loadout that suits your style and show what you can do!
