top of the list is most efficent. bottom is the most useless aganst the enemys

explosives or EK armory shell grenades for shotguns.

fire and high fireate weapons.

(rest of the list below are the trash weapons to use aganst the enemys)

stun guns. stun batons. chloral hydrate.

melee weapons.

poisons such as morbusine. cyanide. and sufforin. can be helpful if all poisons are used at the same time.

any AI humans aganst the enemys.

i belive that should be all. i never tested alien weapons on the enemys so i will not know if its good or not. (if your too lazy to read anything obove. explosives best. fire. smg like weapons. mabye every poison if you dont have any of the good weapons. dont get AI allys to fight them. they will end up getting infected. and no stun weapons. stun grenade will probably do like 4 seconds at best.)
