- This will spawn the Monster Truck, simply eliminate the enemy with it until you win. The achievement will pop once you win.EDIT: As Jdobem, Itzz Sh0wt1m3 & fireiz have pointed out, it is VERY IMPORTANT to view the Postgame once the match is over. So DO NOT just quit out once you have won, ensure you view POSTGAME first.
