If you’re here, you’re not just playing Crime Scene Cleaner… you’re trying to perfect it. And let me be honest with you—this is one of those games where 100% completion isn’t hard because it’s difficult, it’s hard because it’s easy to miss things. One stain, one misplaced object, one hidden room… and suddenly your perfect run is gone.
With the release of Act 2, things got even more interesting. The game now includes five brand-new missions that continue Kovalsky’s story and feel like a proper step toward a finale. These missions aren’t just “more of the same”—they’re tighter, more detailed, and packed with secrets that can easily slip past you if you rush.
On top of that, you now have:
- New achievements to unlock
- New music tracks to collect
- New skins to customize your cleaner
And yeah… that means your 100% grind just got longer.
This guide is built to help you avoid mistakes, understand what each achievement actually requires, and most importantly—not miss anything.
Crime Scene Cleaner Act 2 Guide – 100% Achievements
Before jumping into missions, understand this:
A perfect score requires you to:
- Clean every stain
- Pick up all trash
- Restore every object
- Find all clues
Miss even one thing and you’ll have to replay the entire mission.
There are also Nightmare versions of missions, which you must complete for certain achievements, plus a ton of hidden and interaction-based achievements scattered across maps.
