# How do you make bullets do damagein the BGE?

I cannot figure out how to make bullets (physical bullets, not rays) actually do damage to the enemy (in a first-person shooter). I have tried the collision sensor but I cant seem to make it work.
All I am trying to do is make it so when the bullet hits the enemy, then the enemy disappears (Edit Object: End Object Actuator). The enemy has the physic type: Character and the bullet has the physics type: Static. I am using simple motion for the bullet.
What kind of properties does the bullet of enemy need if any? What should the logic bricks look like?
