The idea for Insomniac Games’ latest title, Song of the Deep, all started with a sub. The developer wanted to find a way to create an underwater side-scrolling game and liked the idea of exploring the mysteries and monsters of the water with a submarine, but the game quickly became more personal than that.
The first piece of concept art for what would eventually become Song of the Deep was of a young brunette girl holding a candle while overlooking the ocean. Insomniac Chief Creative Officer Brian Hastings felt that image captured loneliness, isolation and hope, and found himself imagining a story inspired by his 10-year-old daughter.
The brunette girl became 12-year-old Merryn, who lives a happy life with her father in Ireland until one day he goes missing on his fishing vessel. Merryn has a terrible dream that shows her father trapped under the sea, so she uses her savvy to build her own submarine, the S.S. Eirnin, and delve into the depths of the ocean to rescue him. Along the way, she learns the songs he would sing to her at night about the City of Gold were of a real, fantastical place.
