Sure, Thomas and co. have left the Maze, but that doesn’t mean they’re done running.

A new trailer for Maze Runner: The Scorch Trials, the sequel to 2014’s adaptation of James Dashner’s novel, we get a better look at The Scorch, the decimated Earth outside the Maze that is “hanging on by a very thin thread.”

The trailer warns “the Maze was just the beginning,” so is it possible that they may miss the Maze? When the cast talked to EW at Comic-Con earlier this month, we asked them just that, as well as what’s in store for the characters when they make the “out of the frying pan, into the fryer” transition to the outside world.

“The cost of freedom is that you’ve actually lost a haven,” said Thomas Brodie-Sangster, who plays Newt in the film. “The Glade was kind of like a haven, you could live a fairly nice life as long as you didn’t go into the Maze too often, you’d be all right. Now we’re free, we can go where we want, but we find ourselves in an arguably much worse situation.”

That’s all complicated by a plague sweeping earth called The Flare, which turns its victims into zombie-like beings. But don’t compare them to zombies in front of director Wes Ball: He maintained “our big goal in this movie was not to do the typical zombie.”

Maze Runner: The Scorch Trials opens Sept. 18.
