The Sims 4 game will bring back the ghost and swimming pools for free.

In the report of the Kotaku Australia, the Sims 4 ghost has launched yesterday while the swimming pool is set to launch next month.

According to the interview on Kotaku Australia to the Sims 4 executive producer Rachel Franklin, the Sims 4 ghosts will come in a "wider range of abilities" compare to its previous instalment.

Furthermore, the Sims 43 ghosts can do multi-tasking and can encounter emotional issues as well. "When a ghost Sim gets into a particular mood, their entire character lights up with a particular color - red for angry, pink for flirty, and so forth."

Below is a quick guide from Kotaku Australia on how to reintroduce the ghost Sims to your household and to get started with the afterlife:

When a Sim dies, they become a non-playable ghost.

Use the "Invite to Household" interaction to make a ghost into fully playable member of your household!

Ghosts can have relationships, get married, hold jobs, and others.

Ghosts have a unique post life experience on how they die.

Sims that died by an emotional death can radiate their emotion onto other Sims.

Sims that died by fire have a new interaction available to them, try and not make them angry.

Sims that died by electrocution, when angry, have a unique interaction to break electronic devices.

Sims that died of hunger seek to satisfy their hunger in the afterlife.

Sims that died of overexertion and old age find they prefer to take it easy in the afterlife.

Sims that died by Cowplant have the desire to harm and help the plant world.

Ghosts can possess objects, and they can repair broken objects when possessed.

Ghosts have new interactions available to them, such as "Ghost Scare," "Pass Through," and "Talk About Death."

Level 10 Gourmet cooks have a new recipe "Ambrosia", which can be used to bring a Ghost to life.

There is a new gardening, flower type, the Deathflower, which can be used by a Sim to save themselves or another when visited by the Reaper.
