beatmania IIDX 3rd Style is a music video game developed by Bemani and published by Konami, initially released as an arcade game in Japan on February 25, 2000, and subsequently ported to the PlayStation 2 on November 2. 3rd Style removed the 4-keys mode from previous installments and replaced it with the Light7 difficulty, giving most songs a fully separate, easier notechart. The game also introduced Free Mode and Extra Stage, and featured a new aesthetic.
