To unlock the “John Bucket” skin (a Teenage Mutant Ninja Turtles nod) in Act II of Crime Scene Cleaner, you’ll need to locate Dave’s secret lair. It’s hidden behind a game of darts on the “Amber Alert” level. To open the passage, you must score exactly –301 points by strategically landing darts in the right segments.
How to play darts on the Amber Alert level
The goal is to reduce your score until you’ve subtracted 301 points. You start at 0.
The green bull’s-eye is worth –25 points.
The red bull’s-eye in the very center is worth –50 points.
The board has inner and outer rings. The inner ring triples the segment’s value, while the outer ring doubles it.
For example, hitting the outer ring under the number 20 gives –40 points (20 × 2).
Landing in the inner ring of the same segment nets –60 points (20 × 3).
Hitting the white or black part of a segment scores the number printed on the outside. For instance, landing in the “1” zone is –1 point.
Once you hit exactly –301, a hidden door opens into the sewers. Head inside to reach Dave’s lair.
Behind a wooden panel under the basketball hoop you’ll find a stealable item.
