The forcefields protect the alien lord in the classic version of spelunky.

In Spelunky HD, Forcefields protect the Alien Queen and the Alien Lords. They bounce bullets shot at them; it's adviced to time the shots right before attempting to shotgun an Alien through a Forcefield.

Death caused by rebound bullets show as "Death" with no explanation, just like when the Ghost kills you.
