Trick or Treat is one of those dark adventure games, which are hard to find today. It is a true extravagant point and click that puts you in the shoes of a guy who has recently gotten another job as a care assistant for an old man at the Home Care Center in Devilsville.

You start your work on October 31 and as soon as you arrive at the Attention Center your car is stolen by the former Care assistant. You enter the house and introduce yourself to all the elderly and they all order you to get various items for a Halloween party that are being organized tonight. The discovery of these elements is the first part of its mission.

The Halloween party is your worst nightmare when those innocent old figures in the center turn out to be the members of a dangerous sect in search of someone they can use in performing a blood and voodoo ritual. The ritual, according to their beliefs, can bring their dead leader back to the land of the living. Your main mission is to help them in the fulfillment of this ritual and help yourself out of this hell.
