X-Drone's weapon is broken.

Basically you can beat the x-drone to death because it's weapon, I assume, stops you from going into cardiac arrest and dying like you normally do in crit. So as long as it continues to hit you cannot die and as long as you have a medkit you can get back to full in no time flat. Takes a long ass time to kill it so I don't know if it's "broken".
