Vampire

Vampires are a new game mechanic added onto The Sims 2: Nightlife which introduces vampires as both playable and non-playable creatures to The Sims 2 series. It is also seen in The Sims: Makin' Magic.

The Sims
In The Sims, there are a few notable vampires. One is Vicki Vampiress, a person owning a cart of all-things draconic. There are other two vampires, which are accessible through the spell "Beauty or Beast". You can choose a vampire for both genders, and that will replace the look of the Sim for a while. Becoming a vampire is simply cosmetic, and vampiric Sims will interact normally with other Sims and they have no other noticeable differences from normal Sims.

The Sims 2: Becoming a Vampire

 * Vampirism is transferred via the bite neck interaction.
 * If a Sim is bitten by the "Grand Vampire" or a pre-bitten Sim, he or she joins the world of the undead as well. Initially Sims are bitten only if they have a high relationship with the vampire, however once one Sim is bitten by a vampire any Sim that comes into contact with a vampire has a risk of being bitten, whether or not they are a playable Sim and regardless of the relationship with the vampire. Other Sims can also influence a vampire to bite another Sim.
 * Grand Vampires appear downtown at night and their names are preceded by either the Count or Contessa title depending on the gender. They are easily distinguishable from the crowd by their light blue skin, period clothing, and unmistakable 'bleh'. They also have their arms covering their fangs.

Using the Cheat to Become a Vampire
If you want your Sim to become a Vampire without all the hassle, there is a cheat. It's much easier than trying to find the "Grand Vampire" and the cheat enables you to make your Sim a Vampire in any of The Sims 2 expansions as well as The Sims: Life Stories.

I use the one below to make my person a vampire.
 * Press "Ctrl" "Shift" "C" to open up the "Cheat Window" either in the neighborhood, or on a lot. 
 * The cheat is boolProp testingCheatsEnabled true 
 * When you have the cheat enabled, just hold the "Shift" button down while you "Left Click" on the Sim you want to turn into a Vampire. Many new options will appear. Find the option that says "Make Vampire". Your Sim will instantly become a Vampire. You can also cure your Sim from Vampirism without the hassle of buying a "Cure Potion" by using the same cheat. 

Features

 * When a Sim turns into a vampire they receive the characteristic sharp teeth, red eyes and pale skin. Aliens turn turquoise, Zombies turn dark blue! Servos also can become vampires, with a red eye and fangs.
 * Once bitten, the newly created vampire can bite other Sims.
 * Vampires can transform into bats and fly around, which allows them to fly over low obstacles such as kitchen counters and is a fast alternative to walking for Sims too lazy to run. Vampires can also 'stalk' from place to place.
 * Vampire Sims gain the Irritate &gt; Bleh! interaction which lowers the Bladder need of target non-vampire Sim and can be used regardless of relationship.
 * Teenage Vampires can get a scholarship to go to college.
 * Vampires will sizzle and smoke while exposed to the daylight, and their motives drop very quickly, eventually leading to the vampire's demise. Motives will also slowly decay indoors, or more quickly if they're near a window. A vampire Sim must sleep in his/her coffin or meditate during the day to prevent their needs from dropping.
 * For this reason, vampires are contactable at night but not during the day without drama.
 * The motives of a vampire Sim do not decay at all during the night. This is meant to give them plenty of opportunity to party Downtown all night. They still lose needs when doing some activities.
 * Another additional feature is the fact that the vampire Sims are immortal and will never grow older than the day they were bitten, with the exception of the transition from Teen to Young Adult to Adult.
 * Even if Hunger reaches 0, vampires will not die of starvation.
 * Vampires have no reflection in a mirror. If one is used, the vampire will react and their comfort bar will drop. Disturbingly, while vampires are invisible in mirrors, their wedding rings are not.
 * Occasionally vampires will hiss or go 'bleh' if no other action is currently underway.
 * Vampirism is viral, not genetic, so even if two vampires have a child together the baby will always be human.
 * Vampires can also become werewolves. When they become one, they will look like vampires in the day and werewolves at night. They can bite and savage as well as fly and stalk.
 * Vampires can also become PlantSims which changes their skin color from blue to green. This does NOT cancel out their weakness to sunlight, and even in a coffin, the sunlight need will still go down. Installing sun lamps over the coffin will replenish the need, however.

Re-"Normalization"
If at any time the Sim grows tired of the vampire life, Vampirism can be cured with Vamprocillin-D which is bought from the Gypsy Matchmaker. Vamprocilin-D can also be made by witches. The Sim will be able to go out in the day but will lose all the perks of being a creature of the night.

Wanting and Fearing Vampirism
All Sims except Knowledge sims will fear vampirism, and said knowledge Sims will want it, and once are bitten will fear curing it.

The Sims 3

 * Vampires are not included in The Sims 3. However, using the CAS, you can create a Sim with a similar skintone and red eyes, and if you play with the mouth you can make teeth come out of the mouth, with no more vampire features.


 * On the TV, there is a horror channel, where there is a vampire movie that plays.
 * When fishing at level 8 in fresh water using garlic as bait, you can catch a Vampire Fish.
