A God of War: Ragnarok developer has revealed that one of the game's subtlest sound effects is the sound of their baby's heartbeat from inside the womb.
In a recent tweet, PlayStation senior sound designer Alex Previty revealed what went into creating the sound effects heard during the Spark of the World section of God of War: Ragnarok. In a clip, you can see Kratos looking around the environment as a peculiar echoing sound rings out around him. Underneath that, a heartbeat sound rings out, adding a strangely visceral effect.
