The Catalyzer is a pretty cool gun, and i have proceeded to make Biohazard. It is awesome! However its only flaw that i noticed...
The charge attack.

It can be very damaging indeed. But what if Your target is in the middle of a crowd? Constantly moving? Just can't aim to well?
I, Zxero, Have a solution.

The general plan

Each individual bullet isn't very large. So missing does occur sometimes. What if ON CONTACT with a wall or any other surface the bullet released a small mist around it. The mist alone wont damage the enemy, BUT the mist can set off a charge that has been set on the enemy. This makes it so you can detonate a charge even if enemies are around them, because the mist will reach the charge.

What do you all think? The mist range wouldn't be very large so i don't see to much of a problem.
