What a trick shot changes
The island 2 shopkeeper says a trick shot adds extra cash, and that a trickier shot is better. On a kill, the game builds a list of named bonuses and multiplies their values into one killscore multiplier. That multiplier is what gets stored on the creature. It is also what the Impressive achievement measures.
The names you can see, including 360, No Scope, Headshot, Fly Fishing, and Impressive, come from the game's killscore labels. The numbers below come from the live checks in build 25604825, not from a single screenshot.
How the product works
Start at 1. For each bonus that applies, multiply by that bonus. The order does not matter. Five bonuses of 1.2 are not "5" and they are not "1.2." They are 1.2 multiplied by itself five times.
Bonuses are chosen before the kill is added to the multikill counter. The first kill in a streak therefore does not get a Double Kill bonus. The next kill, if it lands within 3 seconds, does.
Bonus values in this build
| Bonus | Value | When the live check adds it |
|---|---|---|
| Melee | 1.05x | The kill is a melee kill |
| Explosion | 1.25x | The kill is an explosion |
| Endangered Species | 1.25x | The creature's endangered flag is set |
| Double Kill | 1.05x | One earlier kill is still inside the 3-second window |
| Triple Kill | 1.10x | Two earlier kills are inside that window |
| Quadra Kill | 1.15x | Three earlier kills |
| Penta Kill | 1.20x | Four earlier kills |
| Multikill | 1.25x to 1.50x | Five or more earlier kills. The value moves up by 0.05 per extra kill and stops at 1.50x |
| 360 | 1.50x | You turned at least 320 degrees. Stopping the turn for more than 0.5 seconds resets the turn. The bonus lasts 1 second |
| No Scope | 1.20x | You are not aiming, and at least 0.25 seconds have passed since you stopped aiming |
| Quick Scope | 1.10x | You are aiming, and no more than 0.5 seconds have passed since you started |
| Longshot | 1.30x | The camera is at least 25 units from the target |
| Headshot | 1.25x | The hit point is past the creature's head position on its own forward axis |
| Dogfight | 1.50x | You are off the ground and the target is airborne |
| Aerial | 1.25x | Only you are off the ground |
| Fly Fishing | 1.25x | Only the target is airborne |
| One Shot One Kill | 1.25x | The creature was at full health and this hit's damage covered that health |
| Point Blank | 1.10x | You are under 2 units from the target |
| Overkill | 1.25x | Damage exceeds the remaining health by more than 70, and the target is not a boss |
| Last Bullet | 1.25x | The kill was not an arrow, and the held gun has 0 ammo after the shot |
| Finally | 1.10x | The sum of the weapon's shot interval, added once per shot since the last kill, is above 5. A 30-second gap resets it |
| Killsteal | 1.30x | You have landed no earlier hit, and the creature is at or below 30% health |
| Archery | 1.50x | The kill was an arrow |
| Inspect Kill | 1.50x | You were inspecting when the hit landed |
| Quick Switch | 1.25x | The weapon was equipped less than 1 second ago |
| From Beyond the Grave | 1.50x | You are dead when the bonus is checked |
| Noob Kill | 1.01x | Nothing else applied. This also unlocks the Noob achievement |
| Impressive | 2.00x | Five other bonuses are already on the list |
No Scope and Quick Scope cannot both apply. Dogfight replaces Aerial and Fly Fishing when both of you are airborne. Explosion's live value is 1.25x. An unused helper in the same file lists 1.50x for Explosion and is not what a kill calls.
Impressive and 360 no scope
Impressive is appended only after the other checks. If those other checks produced five bonuses, Impressive multiplies the whole product by 2. The Steam achievement then unlocks only if the product, including that 2x, is at least 5.
Five small bonuses can still miss 5x. Five 1.10x bonuses are about 1.61 before Impressive and about 3.22 after it. The label can appear while the achievement stays locked. That is the check in this build, not a reason to copy one kill's on-screen number into a spreadsheet.
360 no scope is a separate achievement. It unlocks when the same kill both counted a 360 and was a no scope. It does not require the 5x product.
Misreadings to skip
- Do not treat the shopkeeper's "trickier is better" line as a published best combo.
- Do not read Finally as "five shots" for every gun. The sum uses that gun's shot interval.
- Do not farm bosses for Overkill. The check refuses bosses.
- Practice on an ordinary creature. The story trophies on the walkthrough are still quest items first.
