Zombie
A Zombie is a Life state that players can turn their Sims into. This creature is a available in The Sims: Livin' Large, and expansion packs of The Sims 2.
The Sims
In The Sims, if a Sim dies, a loved one can plead to the Grim Reaper and engage in a rock-paper-scissors game for the life of the Sim. If the Sim loses, but the Grim Reaper is in a good mood, he'll bring back the deceased Sim as a zombie. Zombie Sims retain all of their skill points, but lose all of their personality points, as well as gain a green tint to their skin. Besides this, zombies act like normal Sims and can die (again... ) like living Sims.
There was also and appearence of a "Frankinstin" Zombie, made by a mad scientist guy, who comes into your house and steals your items. The next day the zombie will come onto your lot. It doesn't have green skin like the sims on the picture beside it and can be found on the cover of Livin'it'Up(or large) and Delux Edition.
The Sims 2
Zombies are only available through The Sims 2: University, The Sims 2: FreeTime and The Sims 2: Apartment Life. In University, Zombies are made through use of the Paranormal career reward. Sims who died can be brought back through the use of the Resurrect-O-Nomitron. If a Sim bids between §998 and §4127 when using the Resurrect-O-Nomitron, a dead Sim will come back to life as a zombie. In Freetime, if a Genie resurrect wish fails, the Sim will return as a zombie. In Apartment Life, one of the evil witch spells is to bring a dead Sim back as a zombie.
He or she returns with a blueish skintone, distorted facial features, and a set zombie Personality. Zombies cannot walk, skip, or run - they move with a zombie "shamble". Skill points are also lost. The new zombie Sim will have a lowered daily and lifetime relationship score towards the Sim who brought them back as a zombie. Zombies are only able to age if they are a Teen. They can get scholarships and go away to College, when they return they will stop aging therefore, they do not die of old age. Occasionally a Sim may react in a disgusted way when a zombie enters a room. Creepily, zombie Sims will occasionally think of brains. While it is possible for Sims to enter relationships with zombies both male and female zombies are sterile. That being said, if a pregnant female or alien-pregnant male is resurrected as a zombie, they will carry that child to term, though the child will be normal, possessing none of the Zombie qualities. Zombies always have low hygiene levels.
