Place it just after the surprise is revealed in your edit, following Enemy Spotted and before Okay Let's Go, so the sequence moves from warning to reaction and then to action.
Over dit geluid
This short Age of Empires II taunt is a single drawn-out Oooh from a game villager voice, lasting just over a second. It lands as a warm, surprised reaction, part impressed and part amused, the kind of sound that follows an unexpected play or a clever move. It comes from Age of Empires II, where it is taunt number nine in the English taunt set.
