Dead Space

As long as you engage in Dead Space’s combat, aiming to cut off Necromorph limbs, rather than aiming for the head or torso, you should easily get this achievement before you finish the game. We’d be absolutely shocked if you don’t get this achievement during your first playthrough, but on the off chance that you don’t, make sure you are accurate with your Plasma Cutter in your New Game+ playthrough, and chop off as many limbs as you can until it unlocks.
