The Smuggler's Run update to GTA Online that was announced last week rolled out today, and it brought with it an unexpected surprise: A new and very familiar-sounding Adversary Mode called Motor Wars that Rockstar described as a "tense battle for survival" in which players scrounge for weapons and do battle inside an ever-shrinking "kill box."

"Blending the adrenaline rush of Drop Zone with the claustrophobic tension of a match of Penned In, this brutal Adversary Mode is a deadly scavenger hunt where second place is not an option," Rockstar said. "Up to four teams parachute into a periodically shrinking kill box strewn with a lethal assortment of guns, explosives and Weaponized Vehicles. Work together, find a vehicle, and fight opposing teams and the shrinking map to survive and win."

Minus the gunned-up cars, that's Playerunknown's Battlegrounds, and while Rockstar doesn't mention the monstrously successful Battle Royale game by name, it's clearly aiming to capitalize on its success. The move also validates our recently-shared opinion that GTA Online should have a Battle Royale mode—and even better, our prediction that it would eventually get one.

The Smuggler's Run update also adds a customizable aircraft hangar, "complete with a complimentary Cuban 800," and seven new aircraft including helicopters, vintage fighters, and even Cold War-era bombers. Naturally, there are also new cars in the mix—the Vapid Retinue and the Grotti Visione—and some sweet new duds to wear out on the town.

GTA Online: Smuggler's Run is available now. Full details are available on the Rockstar Newswire.
