"Nice to meet you... again?"
An android named "Eve" speaks to "you", before a headless corpse apparently known as "The Professor".

Completely devoid of any sort of memory, "you",　together with "Eve" – an android, and the Professor's apparent killer – must uncover the truth of what really happened here.

Use your powers of deduction to unravel the mystery of this sealed laboratory, one revelation after another.

EDEN.schemata(); is a multi-ending sci-fi mystery adventure game, featuring headless corpses, a sealed laboratory, a limbless android suspect/heroine, and an amnesiac protagonist.
The game design and gradually UI change in reflection of your actions.
