The Elites

The elites are one of the strongest covenants in the game. They resemble people but are different colors. The weapons they carry are the Plasma Rifle, Needler, and the dreaded Plasma Sword. The Plasma Sword can kill the master chief in 1-2 blows. Throw a plasma grenade at them to save ammunition. Be careful after you throw it on them, because you will have to run because they may run at you before it explodes causing your death. Watch out for Elites in close combat, because they will melee attack you.
