9. Football!
https://www.youtube.com/watch?v=vdTZNOLMAe8 Hidden footballs are a time-honoured Bungie tradition, with giant footballs making multiple secret appearances throughout the Halo series. In Destiny, it looks like Bungie have once again made a nod to this easter egg, which first appeared in Halo 2. To find the football, make your way to The Tower, then to the area's Plaza. Although there have been varied reports as to where it will appear, it generally seems to spawn on the left hand side, just under the stairs. It's affected by physics, meaning that you can feasibly kick it around with friends. There's also a larger, purple ball that can be found nearby, which is floatier and easier to bounce on your head.
