UMBRA

October the 29th, 1994. Ten years tonight.

Ten years ago, eight-year-old Nell Hale went missing on a school visit to St. Audra's Abbey. The search found nothing.

Tonight her older sibling Robin goes back down with a camcorder and the family torch, into the crypts, the sealed

wards of an old sanatorium, and the drains beneath - to find out where Nell went.

Something lives down there. The brothers of St. Audra called it the Hollow. It does no harm to the one left in the dark. It follows whoever carries the light away.

- A short story-driven horror game, played through a dying VHS camcorder

- Your torch is your only light, and it is what gives you away

- Read what the searchers, the sanatorium staff and Nell herself left behind

- Two endings

- Built on its own custom engine, and it ships with the engine's editor: place props, lights and sounds,

- import your own models (.obj), sounds (.wav) and textures, and play-test your changes
