Secondary tactics to keep in mind to get the most out of your weapons isn't just a good idea, it can completely change how you use some weapons in Campaign, Firefight, and even Halo 3 multiplayer. This venerable tactic is almost never used, but I swear to god, you put it to good use, you'll learn that even the MA5C and the M7 have their advantages. Short, controlled bursts completely change up the ranges you can use certain weapons. If your reticle is covering the enemy completely, and not splashing over too much, you can shoot, accurately, in short bursts no matter the weapon. Aside from that, Plasma Rifles and Pistols can put rounds down range surprisingly accurately, if you take into account how slow the shots travel. Plasma rounds are slow enough, no matter the weapon, to be easily dodged while charging towards the enemy. ...Now, then, it would be absolutely lovely if someone could direct me to a forum post regarding the Classic Achievement. I swear to god, that mother-blam!- who said, "I bet you're stupid enough to try beating ODST on Legendary only using Melee" should die. Make note, that was abridged quote.
