If you are getting pretty ticked cause the boss who throws knives at you keeps on killing you well here's a hint use the shot gut when you are at close range and use the second hand gun at full power but don't use the double barrel shotgun cause it only has 2 shots and also don't stay in one spot while shooting him cause he will kill you pretty fast but doing this is pretty hard though so if you aren't that good of a shot at shooting moving objects practice on the level before the boss and when you think you are ready then try this hint

Whenever you kill an enemy try to think of the coolest way to kill him. For example, if you have some dynamite try blowing up the guys or aim for the explosive barrels. Sometimes the enemies are on platforms that can fall down from you shooting it, the good thing about doing this is that 1) you'll kill the guy on it 2) you'll kill anyone underneath the platform and 3) you'll get legend points. Basically just kill the enemies in the most exotic way you can!
