Trick Shots
Landing trick shots (like a 360 spin kill with no scope) earns bonus in-game currency, shown as a stacking string of named multipliers.
Officially described by the developer as a scoring mechanic layered on top of the core fish/kill loop. Official trailer footage shows the multiplier names directly on the kill-feed HUD: Impressive, Killsteal, Fly Fishing, Overkill, Last Bullet, Point Blank, Finally, Longshot, Headshot, One Shot One Kill, Dogfight, Endangered Species, Aerial, Quick, and Melee. Multipliers stack (e.g. a single kill showing four or five of these at once, each adding its own percentage).
