Plants vs Zombies 2 is a tower defence game in which players defend their lawn with plants against waves of zombies, and Lost City is one of its adventure worlds, themed around a hidden jungle temple. The final wave intro is the short musical sting that announces the last, largest assault in a level, so players know to use their remaining resources and strongest defences. Clips of these world themes circulate widely in gameplay videos, edits and soundboards, where fans reuse the cue to signal a decisive moment, keeping it familiar long after the level itself is finished.
