This week, GTA Online sees the return of yet another Year 2 Adversary Mode. Running Back is a fight for supremacy between two teams of vehicle drivers – one team has to get their Runner (driving a smartcar-esque Panto) to the end of the playing field and into the goal zone, while the other team does their best to keep them out of the endzone.
The new maps in the Remixed version moves from the original tunnels and bridges that hemmed in the teams, and now features custom-designed neon stunt arenas for players to dart back and forth on. They also replace the old off-road buggies that were used for defense and offense with squads of supercars that can use their superior speed to overtake the Runner, or defend them with greater ease.
