Judge Dredd: Dredd vs. Death Hint: Vampires
Rather than waste loads of ammo trying to take down the many vampires that appear in the game just select incendiary shoot them once and when they burst into flames, run away. If you keep moving they will not catch you. This saves ammo. It helps if you shoot them from a distance.
