Released by Bothtec in 1986, this title is a classic action-adventure game. The story begins with the protagonist drifting as a spiritual entity within mysterious ruins that have suddenly emerged from the sea. Without any initial explanation of your purpose, the situation and your ultimate goals are gradually revealed only through your exploration of the depths.
A standout feature of this game is the "Spirit Ride" system, which allows you to possess the bodies of defeated enemies. Since your attack methods, health, and even your social standing change depending on the host you inhabit, choosing which body to possess is the ultimate key to navigating the ruins.
From the strong sci-fi aesthetic of the characters and environments to the fluid animations of humanoid figures and the atmospheric use of sound effects—such as the rhythmic crashing of waves—every element works in harmony. Together, they create a cinematic and evocative experience that truly stood out in the gaming scene of its era.
