A brand new trailer for the upcoming Arnold Schwarzenegger starrer 'Terminator: Genisys' has been released by Paramount Pictures after fans were asked on Twitter to tweet using the hashtag - #TerminatorUnlock.

And, the trailer doesn't disappoint. Not one bit. It has everything. From Arnold back to doing his best to Emilia Clarke playing a younger version of Sarah Connor delivering some awesome punch-lines to Jai Courtney showing what he's capable of, the trailer packs in quite a punch. And, just when we thought we have been shown the best, Arnold delivers that iconic line, "I'll be BACK!" And, he so is based on what we've been shown so far.

"'Terminator: Genisys' is the first part of a standalone 'Terminator' trilogy. In it, John Connor, leader of the resistance in the year 2029, continues the war against the machines. When he learns of a plot to send a Terminator back in time to kill his mother, he sends Kyle Reese to protect her, but the Sarah Connor that Kyle finds is different than what he expected."

'Terminator: Genisys' directed by Alan Taylor (Game of Thrones, Thor: The Dark World) brings back franchise icon Arnold Schwarzenegger as the T-800 Terminator along-side newcomers Emilia Clarke, Jai Courtney, Jason Clarke, Matt Smith, Byung-Hun Lee, and JK Simmons.

'Terminator': Genisys' is set to hit screens on July 1, 2015.
