These rules were found on The Sims 4 Alien Takeover Challenge! — The Sims Forums
Your mission from planet Sixam is to populate the sims world with simaliens – the super race. To do this you must find and kill victims that are human and at every opportunity get a child from these sims in order to make the superaliens (sim/alien combo)
Rules:
Make your sim, they can look however they like BUT the sim must be an alien and MUST wear their disguise at all times except when on their own. – You cannot be found out! (you may use more than one alien, but it will be harder to keep their true identity a secret.)
(A male hyrbid sim might be a good choice as they can impregnate men and women!)
Killing – The Aliens home must contain a basement, this is where you will lock your victims and kill by starvation. (you can kill using cowplants but this is more time consuming) It is advised to first be impregnated by the sim before killing in order to give a life for taking one.
Once your simalien has reached young adulthood they must be moved into the neighborhood
Your sim cannot become employed – they don’t know enough about earth yet! however they may take money off victims to help them survive.
You must have the baby at home to avoid hospital employees discovering your identity!
Your offspring may participate in the mission but once they have been moved out they cannot!
You can only have ONE CHILD per sim before they are killed, unless of course you have twins etc.
YOU MAY NOT kill sims in the chamber just because they discovered you are an alien.
you may move in the victim in order to trap them however,
Once the victim has been moved in, or been woohoo’d with they cannot leave the lot! you cant risk your secret being reveled! KILL EM!
You fail the challenge IF:
– You are discovered as an alien and the victim escapes the lot
– You die
– You fail to fill every home within Willow Creek OR Oasis Springs with at least 3 simaliens
