-
Another Survivor Appears — The pair encounter another survivor while continuing through the tunnels. Characters: Blast Door Scientist, Frances, Scientist
Location: Underground tunnel
-
Evidence Of Dismemberment — They find bodies, handcuffs, a knife, and signs that people were dismembered. Characters: Blast Door Scientist, Frances, Scientist
Location: Tunnel chamber
-
Frances Has Changed — Frances admits that the procedure changed her and left a constant internal ticking. Characters: Frances, Blast Door Scientist
Location: Tunnel chamber
-
The Forgotten Task — Frances believes she has forgotten an important task connected to the experiment. Characters: Frances, Blast Door Scientist
Location: Tunnel corridors
The Force Beyond Memory
Pursuers overtake the tunnels and the survivors escape with improvised weapons as their chances collapse. The scientist finally recalls the occult research, the infinite power source, and the force that erased the researchers' memories.
Key Events
-
Pursuers Enter The Tunnels — Many pursuers approach through the tunnels, forcing the survivors to prepare for attack. Characters: Blast Door Scientist, Frances
Location: Tunnel corridors
-
Lieutenant Restrained — The survivors watch a lieutenant being restrained while men mark him with strange symbols. Characters: Blast Door Scientist, Frances
Location: Tunnel chamber
-
Transformation Process Revealed — The markings suggest that the restrained lieutenant is being transformed into a pursuing creature. Characters: Blast Door Scientist, Frances
Location: Tunnel chamber
-
Improvised Escape — The survivors flee with improvised weapons as others are killed and the tunnels become more dangerous. Characters: Blast Door Scientist, Frances, Scientist
Location: Tunnel corridors
-
Classified Occult Instructions — The scientist recalls that researchers received ancient classified material containing occult instructions. Characters: Blast Door Scientist
Location: Underground tunnel
-
The Hole In The Air — Following the instructions, researchers tore open a hole in the air and found an apparently infinite power source. Characters: Blast Door Scientist
Location: Research site
-
Memories Were Erased — The force behind the experiment manipulated the researchers and compelled them to erase their own memories. Characters: Blast Door Scientist, Frances
Location: Underground tunnel
-
Unanswered Opening — The revelation ends before the scientist explains what lies beyond the opening or whether Frances completes her task. Characters: Blast Door Scientist, Frances
Location: Underground tunnel
