On May 19th, 2022, "MEGALOVANIA", the boss theme for Spoiler:Sans from Undertale, was added to Dance Dance Revolution A3 as a crossover song. The song was notable for having Shock Arrows in both its Difficult and Expert charts, being the first song in the game to do so outside Challenge charts. This aspect also carried over to other Undertale crossover songs "Battle Against a True Hero", "Death by Glamour", and "Finale".

"SURVIVAL AT THE END OF THE UNIVERSE", released for Gold Class on May 3rd, 2023, marks the final BEMANI song by composer Akira Complex, who later passed away in June 2023.

Added on November 1st, 2023, The "BABY-LON'S GALAXY" event pits players against a slew of new boss songs utilizing the "FLARE" gauge. This meter starts at max, doesn't recover upon successful timing, and decreases from any judgement below Perfect. This replicates how Extra Stages functioned between DDRMax Dance Dance Revolution 6thMix and Dance Dance Revolution Supernova 2, which required players to beat difficult songs while grades below perfect depleted the player's Life Gauge.
