Ongeki is a rhythm arcade machine by Sega. Released in July, 2018, players equip three characters that are unlockable and upgradable through gacha mechanics to defeat booses. These bosses are tied to each song in the game's tracklist.
Using the joystick controls, players move their character along the note highway and use the buttons to initiate attacks. The goal of each song is to defeat the boss by dealing enough damage througout the song. Higher scores can also earn the players rewards for dealing "Over Damage".
Each character also has their own affinities and are unlockable through Sega's Card Maker system by payable gacha, or can be unlocked throughout the game by various means.
