A sub-series that includes various Nerf series and other toy brands, Micro Shots blasters are re-shelled Jolt EX-1s that are modeled after other blasters; the Fortnite Micro Shots blasters, instead, resemble weapons from the video game.
The weapon's names are all abbreviated; for example, the blaster based on the game's Legendary Assault Rifle has had its name abbreviated to "AR-L", the letter after the dash indicating its "rarity". This may have been done to keep the ideas of violence away from toy blasters and Super Soakers, the same reason blasters are not referred to as "guns".
Unlike in the video game, the rarity determines the color of the blaster. Yellow blasters represent a "Legendary" weapon; purple blasters represent an "Epic" weapon; blue blasters represent a "Rare" weapon. While the game's weapons themselves are not actually colored this way, these specific colors do represent the rarities in the game, as well as other games with similarly-named rarity tiers.
Interestingly enough, Fortnite action figures are produced by toy company Jazwares, which has also produced products and accessories for the Nerf brand.
