Warner's released an all-new Mortal Kombat trailer detailing Sub-Zero's backstory.

The movie shows how he went on to become the Ultimate Assassin, and why he's come to take part in the Mortal Kombat Tournament. He's not in good terms with Scorpion apparently.

The trailer features little gameplay footage, but makes for an interesting watch nonetheless.

Mortal Kombat releases sometime in 2011 for PS3 and Xbox 360, and is being developed by Netherrealm Studios.
