Ubisoft's left-of-field Far Cry 3 expansion Blood Dragon will be standalone, which means you won't need to have purchased a copy of Far Cry 3 to play it. The news comes via a listing on the Xbox Marketplace website, which points to a May 1 release date and (take a deep breath) the involvement of Michael Biehn.
You should know who Biehn is already, but if you don't: he played Dwayne Hicks in Aliens and Kyle Reese in Terminator, which means that for any high-budget project trading on VHS '80s nostalgia, he's a perfect fit. Just in case the retro-futuristic sci-fi aesthetic of Blood Dragon isn't already abundantly obvious thanks to these screenshots , here's the official blurb on the Marketplace page :
"Far Cry 3 Blood Dragon is THE Kick-Ass Cyber Shooter taking place on a bizarre open-world island crawling with evil. Welcome to an 80's VHS vision of the future. The year is 2007 and you are Sargent Rex Colt, a Mark IV Cyber Commando who's fighting against a cyborg army gone rogue. Your mission: get the girl, kill the baddies, and save the world. Experience every cliché of a VHS era vision of a nuclear future, where cyborgs, blood dragons, mutants, and Michael Biehn (Terminator, Aliens, Navy Seals) collide. Playing Far Cry 3 Blood Dragon doesn't require a copy of Far Cry® 3."
So yeah, this is definitely a thing, and it's coming very soon.
