If you have been following Media Molecule’s newsletter, you should get an invite to the Dreams creator beta today.
The beta allows players to experiment with the game’s in-depth creation suite, making new levels, games, films, and other experiences using the robust toolset of Dreams. The story mode will not be available in the beta.
If you haven’t already signed up for the newsletter, sign ups for everyone else go live on January 4. All experiences created in the beta will carry over to the full game, but you won’t be able to talk about them outside of the official beta forums – you will have to sign an NDA to take part.
Because of the NDA, the beta is only open to people who are 18 or over. You won’t need PlayStation Plus to take part, though. If you want to get involved, make sure you have around 4GB of free space on your PS4.
