GTA Online (opens in new tab) has added a new mode called Bomb Ball to its Arena War (opens in new tab) lineup, and it's basically an explosive, multi-ball version of Rocket League (opens in new tab).
Rockstar calls it "the Los Santos spin on soccer": two teams take to the arena in souped-up cars and try to push enormous bombs into the opposition's goal. Make sure the ball isn't in your half when it explodes.
You can get the idea from the short clip below. It'll be available to play until January 14, and anyone that gets behind the wheel will receive double GTA$ & RP.
It's part of GTA Online's series of holiday updates, which will give players free gifts just for logging on. You'll get a gift every day between now and January 1—they're all listed here (opens in new tab) (scroll down to the "Festive Calendar" section), and they include sweaters, liveries and fireworks.
Additionally, you'll receive two free T-shirts if you play before January 7, which is also the cut-off point for double GTA$/RP for completing certain activities, including biker contract missions and gunrunning sales, and discounts on various items, such as hangars and aircraft. You can read about all them all in Rocktar's post (opens in new tab).
Lastly, there's a new sleek car for purchase called the Grotti Itali GTO, pictured below. You can buy it from Legendary Motorsport.
