Sixam

Sixam is a location, featured in The Sims 3: Seasons and The Sims 4: Get to Work. The name of the lot is a reference to Maxis spelled backwards.

Sixam was mentioned in The Sims 3: Seasons, and functions as a Rabbit hole. Sims and Aliens could travel there by using the Galaxa Space Car with a Space Travel upgrade. They sometimes returned with unique rocks or items.

Sixam is featured in The Sims 4: Get to Work as a secret lot. Sims can access it by constructing a Wormhole Generator whilst in the Scientist Career, by upgrading the Rocket Ship with a Wormhole Generator. Alien Sims may also travel to Sixam by initiating the "Go Home" interaction.

Aliens, as well as alien plant life, may be found while exploring Sixam. Mobile phones do not function there. Fan Theory: Human sims can only explore the one area of Sixam because it is the only area with artificial gravity (as can be noticed by the lack of rocks floating above that area like they float over other areas of Sixam in a noticably Avatar-like fashion. Aliens also can be seen wandering in that area wearing the exoskeletons that they are limited to on Sim-Earth. Evidence of the gravity differentials (other than the floating rocks on Sixam) is the option for aliens to discuss the "unusual gravity" with human sims.
