Power-ups

 are single-shot items used by your Heroes to gain major advantages over the zombies. You can only carry one power-up in addition to the three relics.

Disco Ball
A powerful little item that causes zombies that come near you to start dancing, rendering them vulnerable to attack. Lasts only thirty seconds, but used tactically can give you much needed breathing space.

Healing
Self-explanatory. Green cross that will instantly add 150 Health to your character.

Speed Boost
Self-explanatory. Doubles your Move Speed and Combat Speed. Perfect for slow characters.

Bombs
The little red gravity bomb power-up is useful for situations where you're surrounded by enemies and need to dispose of them fast.

Breath of Fire
Creates a damaging ring of fire around the hero. Excellent for clearing rooms.
