Alright I'm having some problems completing this mission for some reason.I use the Gunslinger+Pandora and the PF594 Argument move I think that is what its called,but anyways you float around in a pod and shoot heat sinking missiles out.I tried jumping up in the air in the middle of the area and using this move to kill most of the enemies,but I always get hit by a Chimera.One of them normally jumps up in the air and starts spinning and then flies at me or a Chimera will shoot seeds and one will hit me.I was wondering is there a better way to beat this mission or is it just luck.

Nevermind I got it, I just used the shotgun and kept walking around in circles until I killed everyone.
