How does that list could be everything? Everything means the list and: Ships, Sparrows, the rest of the Supers, Scout Rifles, Automatic Rifles, Pulse Rifles, Hand cannons, Fushion Rifles, Sidearms, Machine guns, Rocket launchers, swords, melee abilities, Cayde-6, the purple big ball, the soccer ball, Zavala, Ikora, the poor robot that sweeps the same corner, etc. "Everything" covers all the stuff that integrates the lovely word of Destiny.
