Im going to put this up here for everyone. Theres are the methods i used to fight:
The Testers- Get a powerful shot gun weapon upgrade ( make sure it has highest attacking power cuz sometimes there may be 2 versions with different attacking styles) and get defense armor. When fighting, activate run and run across the field until u find one. Shoot the S### out of him and the ones behind em'. but be careful, they have a tendency to fall from the air behind or directly above you. so you will have to run to the other side of the field alot. When running, there will be testers ready to jack your face up with punches. Simple run and hold jump button to jump your highest hight and that should get u safely past them to shoot the S### out of them again. Need to have Hr 2 defense armor to survive those punches, cause you will be punched a lot.... trust me
Big Flies and ZOMBIEZ!!!
This battle is annoying... You will also need a powerful shot gun weapon and defense armor. ( make sure your repeating missions over and over again so you can raise ur hunter rank and earn money so you can buy these things. Trust me, its worth it.) When the fight starts, you run shift from aiming foward and up while shooting. When you hit a fly, they will fall, and thats when you im down and execute them. They may bounce back alittle from the shot gun blast but they should die from 1-3 more shots (depending on the gun). You need to kill 100 flies, so it might be a long fight. always run back and forth to the end of the stage while alternting your shot as well. the zombies are punk a##es. they are just there to annoy you. Kill them quickly so you will have space to run. You might be raped alot by the flyes though, but i your armor is high ( or whatever ) it should be easy to escape it before they start.I finished this mission when i was hr 2 as well.
and last.....( drum roll..)
The Diggity DOGS!!
my tactic is very similar. ([ DO NOT USE SHOTGUN IT WOULD BE EASY TO USE HR3 DEFENSE ARMOR AND HR3 POWERGUN) the most you have to worry about is the dogs from behind. you could jump or ( which i perfer) shoot them while in the air and then finish them off when there down. also you might have to fequently check behind you for dogs. aim down to shot them and aim straight to shoot them while they are jumping. and if you have dogs on both sides of you, shoot then both if they are in growling stance. if you shoot them, they won't attack you for like 4 seconds. so shoot the one infront of you twice and shoot the one behind you twice and repeat, Alternate! You have to stay on your toes for this one
and that should be it for now.
