you were stuck in a facility after an experiment went wrong and an abnormality escaped and caused massive damage resulting in a wide facility breach of these horrific and abnormal entities and a full seal of the underground, While walking you saw one of these things... You were able to hide before he saw you, he had strings floating around him and what seemed to be puppets and dolls around him

.suddenly he appeared right in front of you

"well if it isn't another pathetic scientist.."
