Dead Space 3 - Axes High Trophy / Achievement Guide
168Location: End of chapter 6, refueling the ship.
Weapon: Planet Cracker Plasma Cutter (Only with Rate of fire upgrades with a few others chucked in)
Difficulty: Casual
As soon as you pull the fuel pump down, 2 of the axe guys will come from the doorway. Shoot the first ones arm as he comes into view, then grab his axe with TK. You can put him in stasis or just do it without it, works easy enough both ways. You now want to throw the axe at his other hand and it will instantly die (Won't transform into the whipping thing on casual either, never happened to me with these things on this level). Do the same with the next guy.
Two more will spawn as you move to the doorway, do the same thing again. Don't worry if they breach your area and start hurting you, just line the axe with the renaming hand for a guaranteed kill.
