Each of the 4 characters has an special ability, you firstly need to reach level 5 to earn your first skill point at which time you can press
and use the bumpers to scroll to the skills menu and spend your skill point on the top skill.
Now you will have the ability to use your character's ability, in this case Roland's ability is his Scorpio Turret that is thrown when you press
which releases a turret that shoots and kills enemies.
Each deployment should kill a couple of the early low level Skags around Arid Badlands.All skills have a recharge time once they are used
