Leila, the maid of the Imperial House of Altacruz, and the white tiger warrior Sigma have explored a large part of the Phantom Labyrinth, encountered the authorities of the outside world, and met a few new friends during their previous adventure. Staying in a quiet village, they find out that undead creatures are lurking nearby. Leila is afflicted by a curse and falls into a coma. Sigma must venture into the depths of the labyrinths to find a cure.

Double Solid is a direct sequel to Sonic Dive and has identical visual style, interface, and gameplay mechanics. Like its predecessor, it is an action dungeon-crawling RPG with randomized locations and enemies, with an even heavier focus on grinding and surviving as long as possible during dungeon trips. The protagonist, however, is different: the player controls Sigma (as opposed to Leila in the previous game) and has an access to a different set of skills.
