LIFETAKE:  A Dehacked v3.0a patch for Doom][

  Changes the BFG9000 into a Life Force Stealer.  When fired, the
  weapon warms up like the BFG, then an invisible, BFG-type shot
  is detonated immediately and all targets suffer flash damage
  instantly.  Now the interesting part -- all targets affected
  drop health potions for you to pick up.  One shot can produce
  up to 40 potions.  The weapon consumes the same amount of ammo
  as the BFG.
