I'm sure that Halo assault rifle you mocked up for Halloween 2004 was nice and all. But unless it's also a fully functional Nerf gun that holds three magazines and "a bunch" of darts, you lose. Here's the video proof:
Nerf just can't stop. Last year it was Rambo Jr.'s Vulcan Gatling gun, and now they've raised the bar again—the CS-35 shoots 35 darts from a rotating drum magazine with pump-action auto fire. Holy shit.
Concept sketches. 3D mockups. Prototyping. High speed ballistics photography. If it sounds like weapon development, that's because it is weapon development...just on a Nerf scale.
