[Dead SPACE]Why does Isaac seem almost Godly when he is fighting necromorphs?

Seriously he killed the Hive Mind with nothing but a plasma cutter!

Experience for one. His survival on the Ishimura gave made him not only experienced at fighting necromorphs but also imbued him with the courage to not completely shit his pants in fear. Necromorphs are resilient things but they aren't as unstoppable as they initially seem, especially not when modern technology is so effective at eviscerating them. He's not the strongest fighter in the universe, but the necromorphs are a threat that he knows, and when some big tentacle beast is whipping him around like a ragdoll, he has the presence of mind to find and destroy the weak spots rather than panicking and screaming like a little girl.

Prior to his experience, he was just a guy forced into a horrible situation but he was motivated, not just by survival but by his own damsel in distress. He was still terrified by the horrors of the Ishimura, but he was courageous enough to grab any weapon he could find and wade his way through. His unrelenting drive combined with his desperation led to an unmatched brutality. He doesn't just kill necromorphs, he rips them to pieces. When he was presented with the source of the creatures, a mind fucking, monolithic construct that had been tricking him into hallucinations throughout his time there, he doesn't destroy it conventionally. He drops a god damn continent on it. Isaac's greatest weapon is his brutality.

To add to that, Isaac has a degree of resistance to the marker's mind control effect. That isn't to say he immune, but Isaac is able to look directly into the face of the marker and come out on the other side with his sanity intact. This gives him an exceptional edge, considering the necromorph's greatest weapon is psychological. Necromorphs aren't actually that effective killing machines, they are dangerous of course, but structurally weak (considering they are created by a rapid mutation of dead flesh, this isn't surprising.) Isaac has literally punched them into pieces. Sure they're fast and strong and have swords for arms, but they get sliced apart by power tools pretty easily.

To put it short, the necromorph's greatest weapon is fear, and Isaac is not afraid of them.
