Arknights is a tower defense game for mobile, built around recruiting operators and defending against waves of enemies, and its menus rely on short, tidy interface sounds to keep navigation feeling responsive. The confirm sound is one of those small cues, ripped and shared by players who want the exact in-game audio for edits, streams and fan videos. Because it is so brief and neutral, it travels well outside the game too, working as a generic approval click for gaming content without needing any knowledge of Arknights itself.
