DEEPEST FEAR™ is a sci-fi horror FPS with a retro-future aesthetic. Deep beneath the ocean, a long dormant secret has been unearthed which throws mankind’s future into jeopardy.

As Dr. Danni Carrol, fight your way to the heart of a secret project masterminded by your estranged father and uncover mysteries both deeply personal and terrifying in their implications.

Using real time fluid simulation, fight otherworldly entities which manifest spontaneously from any water source, all while the environment around you can flood and take in water at any moment, sweeping you away with unpredictable currents, plunging you into the suffocating depths.

Deepest Fear combines Metroidvania level design in the context of a classic FPS immersive sim, where the game’s setting is a puzzle to unravel and where creativity and improvisation are your greatest assets.

Channeling the spirit of iconic and subversive 1980s horror action films such as The Abyss, The Thing, The Fly, and Total Recall, and more broadly the cinematic canons of James Cameron, John Carpenter, David Cronenberg, and Paul Verhoven, Deepest Fear aims to stay true to our inspirations’ blend of visceral horror, vivid characterisation, and confrontational storytelling. Meanwhile in the realm of interactivity, our thoughts are never far from titles such as Metroid Prime, Half-Life 2, System Shock 2, and Dead Space.
