The action-packed trailer for Michael Bay’s Transformers: Age of Extinction has debuted with an explosion.

The fourth Transformers movie stars Mark Wahlberg playing the character of Cade Yeagar, a mechanic who is struggling to make ends meet. He then stumbles upon a Transformer and finds government agents after him demanding to know the whereabouts of the Autobots’ leader, Optimus Prime.

When ET visited the set of the movie while they were filming, Wahlberg didn’t reveal much about the movie, but his character tinkers with something and everything gets a little crazy. Now that the trailer has been released, it is evident that Wahlberg was referring to tinkering with Optimus Prime.

In 2012, Bay mentioned in an interview with Hero Complex that the fourth Transformers film will be the last for him and that the plan is to leave it in the “best hands possible.”

The trailer features Dinobots, and according to reports, there are also two new Autobots that will be making their debut appearance in the fourth installment. The two remain to be unnamed, but sources say that one is a 1,200-horsepower blue and black Bugatti Grand Sport Vitesse and the other is a green C7 Corvette Stingray. Hound, a jeep in the Transformers animated series, will also be making an appearance in the film as a camouflaged tactical vehicle.

Also apparent in the trailer is the upgrade of Optimus Prime’s body from a Peterbilt Model-379 in the last Transformers film, to a custom-built Western Star truck. Another upgrade is Bumblebee, which was changed from a Chevy Camaro to a vintage 1967 Camaro SS that was modified.

Transformers: Age of Extinction also stars Nicola Peltz, Kelsey Grammer, Li Bingbing, Stanley Tucci, Sophia Myles, TJ Miller, and Jack Reynor. The film hits theaters on June 27.
