The bad news is split screen does not qualify you for this achievement - Xbox Live only. The good news here is that Smart Match works in this game A LOT better than in the Xbox One version. So finding someone to play with should not be a problem. If you're not getting matched up with someone, your best bet is to set up a gaming session right here at Trueachievements. Time counts for both players in the game.
Edit: Yeah, nobody is going to be online at this point in the game's life. Boosting sessions away!
