With South Park creators Trey Parker and Matt Stone showing off South Park: The Stick of Truth on Microsoft's E3 stage, THQ has dropped a whole raft of new information regarding pre-order DLC too, and a March release date for Obsidian's RPG.

First of all, here's details for the pre-order DLC pack that's up for grabs:

• Good Times With Weapons Pack - THQ is happy to offer exclusive weapons and costumes when you preorder South Park: The Stick of Truth. The Good Times With Weapons Pack, based on one of the most popular South Park episodes of all time, includes destructive items no fourth-grade martial artist should be without. With the Bulrog Chicken Attack, summon the devastating ninja powers of Bulrog and turn your feeble enemies into chickens! BLAM! "Nya-nya-nya-nya-na naa!  Now you are a chicken!" With Cartman's Kick-Ass Sai, the ultimate weapon of destruction, penetrate even the most evil of villains! Harness the fiery sting of the Sai to slash and cut your way through South Park! Rounding out the Good Times With Weapons Pack is the Samurai Costume. Show off your brute muscle with this bad-ass getup, complete with samurai headgear, a super-sweet cape, and the toughest cardboard armour this side of Takagawa. Suit up, and prepare to unleash the ultimate pwnage!

There's also three further DLC packs that have been confirmed for South Park: The Stick of Truth, with each offering a standalone adventure with its own story, taking you to never-before-seen parts of South Park.

South Park: The Stick of Truth is due to launch on March 5th, 2013. Check out three new screenshots and the trailer below.
