No one knows exactly what to expect from Arnold Schwarzenegger’s latest movie, but one thing is perfectly clear — there will be explosions. Exploding cars, exploding helicopters, and a flipping school bus (explosion unverified) all play prominent roles in the latest Terminator: Genisys trailer.

The Austrian Oak himself unveiled the video today, in all its gun-toting glory.

It turns out there’s a method to Arnold’s socia media madness. Hours before posting the trailer, Schwarzenegger fired off a bevy of posts featuring the #TerminatorUnlock hashtag. The premise is simple; use the hashtag, unlock the trailer, enjoy the carnage. Follow along here and make sure you’re in on the action!
