Hop-Upattachments are special weapon attachments that greatly impact the weapon's performance. One Hop-Up attachment can be equipped for each available Hop-Up slot the weapon has. Weapons usually only have one Hop-Up slot available, except for the Bocek Compound Bow, which has two. The available hop-ups change every season.
Can be triggered when there are 2/2/3/3 or less bullets remaining in the magazine for Wingman and 5/7/8/9 or less bullets remaining for Hemlok.
Successful reload overloads the magazine by 2 bullets for Wingman and 6 bullets for Hemlok. This amount is unaffected by the level of the magazine or how many bullets were remaining upon reload.
Reload time reduction is 31% for the Hemlok (from 2.4s to 1.75s) and 40% for Wingman (from 2.1s to 1.4s).
Season 16 onwards (integrated into Hemlok Burst AR)
The damage multiplier differs with each weapon: the Alternator has a multiplier of 1.2x, the RE-45 Auto had a multiplier of 1.7x (reduced to 1.3x when integrated), the L-STAR EMG had a multiplier of 1.6x, and the Peacekeeper has a multiplier of 1.25x.
The Turbocharger is the most persistent hop-up, having appeared in 17 out of 20 seasons. The Quickdraw Holster is the most fleeting, having only appeared in two seasons.
The Graffiti Mod hop-Up was accidentally leaked early in the first Hunt of "The Broken Ghost" quest, where it spawned in one of the loot bins.
The Splatter Rounds hop-up used to increase magazine capacity by 15% (essentially mimicking Rampart's Modded Loader passive), but this was deemed too strong.
There were no voice lines for the Kinetic Feeder hop-up until Season 13, meaning it took 3 months for the hop-up to get voice lines. This is the longest time that a new hop-up has been released without a voice line to accompany it after the Boosted Loader.
