Fps or 3rd person enemies

[poserpal]

Hi.

I am starting to work with blender and i want to create fps or 3rd person games.
I know how to create an enemy that shoots at us with weapons, but i want to know how to make an enemy kill our character by hitting us with his hands, for example.
I obviously need the animation, but how do i make the blender engine recognize that i am being hit with just the hands of an enemy? I hope i have explain well what i need!

I really need a good enemy tutorial that show how to create an anemy that doesn't need a gun to kill us!
Does anyone know of one?

Thank you.
