Shade: Wrath of Angels

Our hero receives a strange ominous letter from his brother, who asks him to come to a small town in the mountains. In addition to the letter, the envelope also contains a strange object, remotely resembling a key. He doesn't hesitate for a moment because he suspects that his brother is in danger and immediately sets off on his journey.
As the story progresses, our hero undergoes a thrilling adventure in which he passes through 4 time periods - the present, the Middle Ages, ancient Egypt and the shadow realm in which everything is different than it seems. Along the way he solves quests and fights Demons, Angels, Mummies, Rats, Shadows and other creatures. His quest is unique: to collect the torn soul of an angel at any given time. If he wants to see his brother again, he must not fail.
