South of Midnight is "10 to 12 hours" long because its story unfolds within a single day: "There's a kind of urgency to it"

South of Midnight developer Compulsion Games has revealed the action-adventure game's runtime, with the story taking place in the span of a single day.

"It's 10 to 12 hours," gameplay director Jasmin Roy tells GamesRadar+ of the average time it will take to beat South of Midnight's 14 chapters.

So you start your adventure in the morning, and it ends at midnight."

This means the game will take players through different environments as the clock ticks forward, each with "their own really specific mood, which would then reflect the type of story being told in that moment." Compulsion has already outlined four biomes in a half-hour documentary that premiered last year – the swamps, the Delta, the Appalachians, and a New Orleans-inspired area – but it's news to us that she'll be
