As it stands the variations between sparrows in-game is spread between three types. Type A has standard boost/braking. Type B has upgraded boost (Vault of Glass/Crota's End). Type C has flippy-diddly spinning mechanics. Extended mounts include the Fallen Pike/Heavy Pike, and Cabal Interceptor. Currently, none of these mounts allow for multiple player mounting, I.e two or more players riding the same mount.
What are the possiblities if two player sparrows/mounts became available? For example, an upgraded sparrow that allows a second player to sit on the rear, facing backwards with the ability to use equipment?
Any thoughts?
