Skull & Bones is the first video game led by developer Ubisoft Singapore, which drew inspiration from the naval battles of Assassin's Creed IV: Black Flag.
The game began development in 2013, being initially envisioned as an expansion
then an MMO spinoff title under the name Black Flag Infinite.
It was then spun off as an independent project, in part due to its initial technology becoming outdated.
According to a Kotaku report, the game has undergone multiple changes in direction and scope during development, exceeding its budget multiple times.
