Things You'll Need
Instructions
Begin the game and choose the "Paranormal" career path.
Work on the paranormal career path until you receive the Resurrect-o-Nomitron as a career reward. Place this device in your house.
Kill one of the Sims in your house. You can do this by setting the Sim on fire or drowning it in a pool.
Have another Sim in your house use the Resurrect-o-Nomitron. When using the device, select the icon of your recently deceased Sim's face.
Insert 998 Simoleans into the device, then use it again and insert another 4,127 Simoleans. At this point, your dead Sim will be resurrected as a zombie.
