Klang 2 – an epic fighting game based on electronic music. Actions and other elements appear in time with the sounding soundtrack. The rhythm action game asks the player to listen to the beat and music to take the right actions and progress through the campaign. The plot centers on a guy named Klang, who finds himself imprisoned in a mysterious and remote prison where the country's worst criminals are collected.

The main character hones his rhythmic combat abilities based on an audiovisual simulation. Gradually, the difficulty level increases, and the user will need to react faster and press buttons, successfully blocking enemy attacks and attacking in response. The gamer is able to attack an opponent with fireballs, dodge opponents' projectiles, or inflict significant damage with special lightning.

Each battle combines elements of dynamism and rhythm. The campaign consists of 30 consecutive levels, where new opponents gradually appear and the style of music changes. The player can select the replay speed from low and high. The combat system is presented in a semi-procedurally generated style, which means that tracks will never sound the same. Bosses that appear change the gameplay rules for the rest of the playthrough.
