Alpha Strike Introduced in August 2019, Nerf Alpha Strike is a blaster line priced much lower with and built more cheaply compared to other Nerf lines.

Many Ultra blasters are black and white in color, with “ULTRA” emblazoned on the side in gold text.

As of 2021, the latest blaster in the RIVAL line is the Helix XXI-2000, designed curve shots in multiple directions. Sub-series of RIVAL include: RIVAL Camo: Blasters re-skinned with a camouflage
