Early on in DR2 you will face off against fellow motocross racer and batsh*t crazy psychopath Leon. He can be a little tricky at low levels but there's an easy way to take him out without exposing yourself to harm. How to- Stock up on whatever firearms you can get your hands on and run up to the sign for the Silver Strip, from there cimb up on the small wooden platform that makes up the sign. Once your there get your gun ready and watch Leon as he circles around the rocks. Once every lap, he will stop to taunt you leaving open to headshots. Put a few rounds in his skull every time he does this and you'll wear him down in no time. Note that while the sign will prevent having to fight off zombies while fighting Leon (they won't be able to climb up after you) every now and then you may see one get smart and get up on the sign. When this happens just use a melee weapon to knock them back down and go back to shooting Leon. If you run out of ammo run away from Leon and up onto the silver strip and look for security officers (they usually have handguns).
