Well, our modern day weapons aren't going to do much against Necromorphs, outside of maybe explosives. Shoot a Xenomorph in the head, and it is dead, Necromorph... not so much.
While Xenomorphs can have some vareints, based on what ever the poor creature the chest buster popped from. However, no subspecies is very different from another, an Alien that popped from a dog will walk on four legs, but has very little in the ways of differences from the human spawned ones. On the other hands, Necromorphs have dozens of seen forms, some tiny, some that can shoot out things, some utterly MASSIVE. We won't be able to come up with a single "one size kills all" plan to deal with them.
Unless we are able to quickly bomb out where Necromorphs origin infection point, incinerating any corpse before they can be reanimated, we would be all kinds of screwed. Necromorphs are slower, but they are MUCH harder to kill with standard firearms. We would be under an unstoppable Zerg Rush we would need Nukes and mass fire bombs to combat. A slow, and very horrible, slaughter of humanity awaits.
