Okay, okay, we've had a pretty exciting day. But Far Cry 3? That's pretty damn exciting. The game was revealed during Ubisoft's E3 press conference this afternoon, featuring a thrilling few minutes of murderous gameplay, and confirming a mess of hints that the game is in development.

The gameplay demo kicked off with the game's main character being thrown down a murder well, attached to a rock, and presumed dead. Rather than simply giving in, he struggles free, only to fight through a couple dozen more lackeys on his way to hijacking a helicopter. On the way, he sneaks up and shanks a handful of bad dudes, as well as taking cover behind various bullet sponges. Frankly, it looks like fantastic madness. Beyond an amorphous 2012 release date, no other details were provided, unfortunately.

Update: Ubisoft sent over the official press release on Far Cry 3, which outs the game as an Xbox 360, PlayStation 3, and PC title. It also details the game's main character, Jason Brody, and his desperate struggle for survival on a desert island gone crazy. FC3 is being developed again by Ubisoft Montreal, though this time around the studio will get some extra help from Ubisoft Shanghai and Ubisoft Massive. Head past the break for all the official details.
