, Guillermo del Toro’s epic sci-fi actioner, has revealed a first trailer, which you can watch below.

So far, the marketing team have played it relatively coy, with only a minimal amount of stills released. Things began to hot up with the release of some (including some of an attack on San Francisco), and the was launched.

Now, a full trailer’s been released, giving the world a glimpse of the carnage revealed at .

The premise is an easy sell: Jaegers (giant humanoid robots piloted by Earth’s finest) are called into action to fight off the global threat of incoming Kaiju (enormous monsters in the Godzilla vein). Sounds cool, right?

There’s a genuinely terrifying scale to the action, with the set-pieces promising to be more visceral and involving than most films that contain giant robots.

And the trailer’s jam-p🌸acked with cool touches, from a peek inside the workings of a Jaeger, to Idris Elba's sure to be immortal battle-crℱy, "Today we're cancelling the apocalypse!"

An official synopsis has also been released:

"When legions of monstrous creatures, known as Kaiju, started rising from the sea, a war began that would take millions of lives and consume humanity’s resources for years on end. To combat the giant Kaiju, a special type of weapon was devised: massive robots, called Jaegers, which are controlled simultaneously by two pilots whose minds are locked in a neural bridge. But even the Jaegers are proving nearly defenseless in the face of the relentless Kaiju.

"On the verge of defeat, the forces defending mankind have no choice but to turn to two unlikely heroes – a washed up former pilot (Charlie Hunnam) and an untested trainee (Rinko Kikuchi) – who are teamed to drive a legendary but seemingly obsolete Jaeger from the past. Together, they stand as mankind’s last hope against the mounting apocalypse."

Pacific Rim opens in the UK on 12 July 2013.
