Young Souls is a cooperative action RPG following twin siblings Jenn and Tristan, who descend into an underground world of goblins after their adoptive father goes missing.

Up to two players fight side by side in brawler-style combat, upgrading gear, stats, and abilities as they progress through the story, which unfolds through hand-drawn cutscenes. Its mix of beat-em-up action and RPG progression rewards experimenting with different weapons and equipment, and it can also be played solo by swapping between the twins.
