BlackShadows

BlackShadows is a short first-person horror game. The player controls a young female scientist imprisoned in a dark, empty research facility. Completing the game requires looking for keys and using them to open doors. On her way, the heroine is followed by a malevolent evil force; the only thing that stands between her and death is the light of her flashlight, and running out of batteries means game over, forcing the player to look for spare batteries.
