The February 21 Nintendo Switch Partner Direct concluded with the surprise announcement of Endless Ocean Luminous, a new title in the Endless Ocean series of underwater exploration games. The game retains the original Endless Ocean titles' focus on exploration over combat or puzzles. However, the addition of a constantly changing underwater layout, larger sunken ruins to explore, and prehistoric and mythical fish species brings to mind the Subnautica series as a potential influence on upcoming Nintendo Switch title Endless Ocean Luminous.
