The phenomenally popular battle royale game PlayerUnknown's Battlegrounds made its console debut earlier this week when it released on Xbox One, and it's already proven to be very popular on the system. Those who may be looking to jump in to PUBG but don't own an Xbox One yet will soon have a chance to pick up both at once, as Microsoft is bundling the game with its new Xbox One X for a limited-time.

Beginning December 17, those who purchase an Xbox One X in participating regions will get a copy of PUBG (which contains a download code for the game) right out of the box at no additional cost. The promotion only runs through December 31, however, so you'll have until the end of the month to score a free copy of the popular survival game with your new Xbox One X.
