Not all front Energy Sword swipes are though. The melee lunges are mostly 1 hit kills for lesser enemies, but higher order elites and brutes take two or three usually. Or so I've noticed, I think..

One thing I do like though, the Hunters are actually a shit load harder this time. Unless you have a scoped gun, or are shooting from behind, you will most likely not hurt them. They were fucking cake in HALO, and now they are actually formiddable. If you get two of them in close quarters, they are a pain in the ass!
