Fans of Uncharted 4: A Thief's End might still be found playing the online modes survival and multiplayer, and if you haven't reached the level cap yet you might want to clear your calendar for the next three days, as Naughty Dog has announced that they will be rewarding players with double experience points from January 27 to 29 in both mentioned modes.
Besides, going online with Nate and the others could make the wait for Uncharted: The Lost Legacy feel shorter. Are you a continued fan of Uncharted 4's multiplayer, or was the single player the only part that interested you?
