As GTA Online continues to grow and grow with no sign of slowing down, Rockstar of course is not going to stop supporting the mode with new content and activities anytime soon. The developer today announced the newest updates for GTA Online, which include a new mode, a new vehicle, discounts, and more.

The new mode is called Dogfight. This is a 1v1 aerial battle mode where you'll get into a plane and try to take down your enemy. Coinciding with the launch is the nice bonus of double GTA$ and RP now through November 13. The new vehicle in GTA Online this week is the P-45 Nokota, a classic plane that you can pick up from Warstock Cache & Carry and then use it for the new Dogfight mode if you want.
