With just a few weeks to go until the new season of 'Stranger Things' is released, the final trailer has been unveiled.

Previous Season 3 teasers released by Netflix didn't give much away, and fans were left disappointed that there wasn't a whole lot about the Upside Down in any of them. In fact, there wasn't a lot about anything.

However, it looks like the latest promo clip poses a lot of questions as we see the return of the Mind-Flayer, apparently speaking though Max's older brother, Billy. The many-tentacled villain seems to have found its way back from the Upside Down (despite Eleven closing the gate in Season 2), as it promises to end Eleven and her friends, the town of Hawkins and then... 'everyone'.

The new season of 'Stranger Things' premieres on July 4th.
