"Nerve gas was developed a long time ago on out world as a weapon of war.  The exact chemical compounds vary from type to type, but they disrupt the Neurotransmitter's and prevent your muscles from relaxing, in effect paraysising the target within second.  The infected lose control of their body and have difficulty breathing, then begin to spasm.  Eventually dieing from suffication due to the spasms.  Even if the flood do not breathe breaking down the neurotransmitter's to paralyiss them would make them much easier to to handle, sending sweeping units over the world to just wrap things up.  As for destroying the ships, if we weaponize the nerve gas it can be distrubtued by missles, and we can install a destruction sequence that can be triggered by flag ships kept away from the battle, constant communication to keep a beed on the fight and allow for an immediate answer to the flood infecting the ship, then we don't waste any time fighting to destroy oen of our infected ships, we push a button.<br/><br/>092 glanced over towards his higher ups without tunring his head, curious how surprised they would be that he knew so much about the weapon.  092 was always looking for new ways to fight his battles.  Nerve gas just didn't have a safe way to protect your own from residual effects.  Even air tight armors meant that you coudl carry it back onto a ship.  So he stopped his research, but it still  might prove useful.<br/><br/>"We'd just need to see how much they change the nerve cells they harvest from the bodies to engineer a proper nerve agent."
