Red Death was designed as an auto rifle. You can see your ship being stored if you run to the tower hangar. Dragons Breath is designed after the Halo 3 flamethrower, hence the name. All three races use to have different stories. That ship you find in the cosmodrome is actually yours in another storyline when you would visit the cosmodrome as a last planet. The Destiny logo can be seen in the footprint of the astronaut in the first cutscene. Destiny was actually the workingtitle of Project Tiger, but they've kept it. I believe Bad Juju was designed as a scout rifle. Handcannons used to be special weapons.
