The Callisto Protocol: Infected Uprising

"You survived hell... but hell remembers you."

Callisto Protocol: Blood Echo plunges you into a new kind of horror — where the screams of the past echo through the walls, and every step could awaken something forgotten.
Hear the voices. Feel the fear. Run... if you can.

New chapter. New threat. Same darkness.
Are you ready to hear the Blood Echo?
