Alien



An Alien is a life state in The Sims 2 for PC and Mac, console, and Nintendo DS. Unlike other life states, they do not have any special properties or abilities, other than their appearance. Technically, playable aliens who appear in The Sims 2 are Sims with an alien appearance. The alien eyes, skintone, etc. are not normally available in Create a Sim, but can be unlocked by using Testingcheatsenabled to enter the CAS debug mode.

Aliens are not featured in The Sims 3, however it is possible to create an alien in Create a Sim. While alien abduction can occur in The Sims, aliens themselves do not appear, and creating them would require the use of custom skins.

Ahem, Aliens are very sexy beasts :D

Physiology
Hybrid children can inherit normal looking noses roughly 2/3rds of the time, though the remainder can inherit the infamous slits in the middle of the face. 80% of the time, green skin is inherited (100% with first-generation alien hybrids, though they can have human-skinned children, assuming that their spouse isn't green), though there are some cases of children inheriting Sim skin tones, allowing them to blend into society unnoticed, assuming they did not inherit erratic facial features. Flamenco Caliente and Jill Smith are both prime examples of this. However, there are times when only partial resemblance is inherited. Those with Sim skins never inherit black eyes, though it is possible for green-skinned hybrids to inherit dominant Sim eyes instead of black eyes. Typically, there is minimal ear difference. Long, gaunt faces are commonly inherited.

Since the alien parent usually has a perfect genetic personality (10 nice, 10 outgoing, 10 neat, 10 active), this is also partially inherited and passed on, which can last for generations before finally being diluted.

How to become impregnated by Aliens
There are five ways to become impregnated by Aliens in The Sims 2. Two ways are legitimate and three ways are via cheating, which poses a risk of the game being damaged if debugging tools are not used.

Normal gameplay

 * Telescope - A male adult Sim can stargaze with the Farstar e3 telescope until he gets abducted. The chances of this are at a modest 0.05%, which remains this way unless manipulated by mods or hitching a ride with the FreeTime aspiration point bonus. After the Sim is abducted, they will return a few hours later, pregnant with an alien hybrid.


 * Electro-Dance Sphere - If the player has the Nightlife expansion pack, male Sims can also be abducted using the machine if they have been abducted previously with either 2 telescopes, or if very lucky, the Dance Sphere. It is rumored that the the chances increase if a Sim uses the Dance Sphere with 10 Body points. This method varies in effectiveness between 1.65% to 2.5% depending on how many times the Sim has been abducted previously, but the chances are significantly higher than a telescope, regardless of how low it can get.

Cheating

 * In-game Debugging Mode - Entering the cheat  then shift-clicking on the telescope and choosing "Debug - get Abducted". After this point, the process continues as normal. Newer expansion packs have made this cheat impossible. All the Sim will do now is walk up to the telescope and cancel the action. Beware, using this cheat may corrupt your game.


 * The Tombstone of L & D - Initiating the  cheat, then, shift-clicking on any Sim and spawning the Tombstone of Life and Death allows the player to open up testing options to initiate quick pregnancy in any gender. The options "Make me alien pregnant" and "Speed up my pregnancy" in the pie menu make this the fastest, albeit riskiest method of all. Both options will work, regardless of gender.


 * Create a Sim Debugging Mode - Enabling the  cheat allows the player to hold Shift+N to unlock alien skintone and eyes, along with hundreds of other features hidden by the game in CAS. It is turned off by holding Shift+M. This method of cheating is the safest, as there is minimal opportunity for the game to crash as it likely would in normal gameplay. Furthermore, CAS only creates Sims without any varied recessive traits or extreme personalities that would be inherited with normal hybrids such as 0% chance getting abducted when stargazing as an alien-sim hybrid, although these values can be edited by those knowledgeable enough to change these values in programs such as SimPE.

The Sims 2 console versions
The player can select an alien skin in the console version of The Sims 2. If a Sim has an Alien skin, their eyes will be widened and the colour black.

The Sims 3


Aliens are not featured in The Sims 3 base game (or any expansion pack to date) however it is completely possible to create them, without subtle details like the blue gums and full-black eyes. Additionally, subtle differences in green skin tone can be made, which wasn't present in The Sims 2.

If The Sims 3: Late Night is installed, a prop featuring a baby alien similar to the ones in The Sims 2 can be found at the PlumbBob Pictures Backlot in Bridgeport on certain days of the week. However, whether or not aliens will ever return in The Sims 3 is still unknown.
