Hack the smart gadgets in the house, such as lights, doors and various appliances, to set up traps or improvised weapons from objects in the house.
Hide under the furniture, set your trajectory and enter the enemies, knocking them down with such force that they fly, then gnaw them when they are on the ground.
But be careful not to leave too much blood on the carpet, as you will need to make sure the house is clean before the family gets home.
Only you can save Christmas and show these thieves that justice is bad.
