1. Energy Sword - Halo
The energy sword epitomizes everything that's cool about the Halo franchise. A sword...made of pure energy. Whether you're playing through the campaign, or kicking-ass online, the energy sword may be all you need. As well as looking like a God-given weapon, it's pretty effective two. Wait round the corner and Slash. Your enemies are dead pretty quickly. Sadly, we'll likely never see this beautiful creation.
