Overkill

=Description= Adds the leftover damage of a weakspot kill onto your next weakspot hit.

This might be a reference to OVERKILL Software, another game company which Coffee Stain Studios has an apparent partnership.

=Gameplay Notes=
 * Overkill stacks indefinitely and carries into subsequent waves, potentially allowing one-hit-kills of most enemies.
 * Static Discharge and Headache become quite powerful if combined with Overkill, since their damage is percentage based.
 * Snorkers present an ideal situation for racking-up large amounts of overkill damage in a relatively short period, as they have low health, prominent weakspots, and usually spawn in larger groups.
 * Though Overkill can be very potent in a normal Campaign, the leftover damage reduces significantly if enemy health increases, making it less effective in Survival Mode or against heavily mutated enemies.
