The free download adds a "Challenge" feature to track friends' minigame scores. Appropriately, the DLC adds six new minigames: Super Striker (for Soccer), Pinvaders (for Bowling), Rapid Runner (for Track & Field), Target Smash (for Table Tennis), Fruit Splatter (for Volleyball), and King of the Ring (for Boxing). It also includes new games for the multiplayer Party Play mode, and three new "crazy" Party Play mascots: "Zippy Zombie" (okay, so maybe it's not all fresh), Champion Chicken, and Sportastico. Check after the break for descriptions of the minigames.
MS also announced that new DLC will arrive for Kinect Joy Ride on January 4. The "Chevrolet Car Pack" adds the Camaro, Corvette, and Cruze to your game. It's free -- all you'll have to do is ... select a Chevy ad in XBLM.
Update: Catch a trailer after the break -- a trailer that refers to the set as the "Samsung Party Pack."
