Explosive Arrows are just standard grenades with a longer reach. Very useful.

BOW Gas grenades (which contain the P-Epsilon BOW Gas from RE2) deplete a monster's HP by 1/2 every time you fire. It was previously thought that BOW gas was useless, because every other numbskull that has tried them has only tried to use BOW Gas alone. Only 3 exist in the whole game, in the hallway with the metal detectors. Currently, testing whether it is worth it to go out of the way for BOW Gas at all.
