Lineage II is a fantasy MMORPG developed by NCSoft and first released in South Korea in 2003, building a huge player base across Europe, Russia and the Americas. Its level up cue became one of the game's most recognisable interface sounds because players heard it after hours of grinding for experience. As clips and private servers spread online, the chime escaped the game itself and was reused in streams, montages and soundboards as a universal signal for progress, which is why La2 and Lineage 2 fans still search for it today.
