In this guide, I'm not going to show upgrade trees, tell you where you can find each weapon (if you have the free DLCs, you start with free versions of every weapon available in the bank anyway), suggest certain upgrades (damage/duration is pretty much the most important one for every case, as it conserves ammo), or tell you how to play the game. Some tools are just better at severing limbs than others, so naturally they would make better weapons against Necromorphs. The reasoning behind this is that weapons are traditionally designed to kill by blood loss or destruction of internal organs, which Necromorphs are not susceptible to. Most of the "weapons" in Dead Space are actually mining or engineering tools which are clearly not OSHA compliant. Before you complain about the various aspects of this guide, keep note that it will contain a lot of personal opinions formed from experience in addition to the premise of the weapons themselves.
