Cancel the Autopsy is the first MK Challenge that takes place on the Police Station map. This guide walks you through what you’ll need to do throughout the trial.
Your objective is to find three keys located across the basement of the Police Station, and then use those keys to lower reagents into a grinder.
You begin in a small hallway area just before the gymnasium. This area is safe, so take some time to explore, gather items, and look for posters if you’re aiming for an A+ grade.
When you’re ready, enter the gymnasium and press the button to activate the grinder.
Finding the Correct Keys
You’ll need to locate the correct key in three different sectors: A, B, and C.
You can tell which key you need for each sector by checking the three TV screens in the gymnasium, which display the symbol tied to that sector’s correct corpse.

Each sector contains one correct corpse (matching the symbol) and several decoys with incorrect symbols.
Search each sector carefully until you find the corpse with the correct symbol, then retrieve the key inside. As you walk around, question marks will appear showing you the location of corpses – once you are close enough, look at the body to determine if it’s the correct one.

Tip: Remember that searching the wrong corpse will deal a small amount of electrocution damage.
Each sector also features a different enemy you’ll need to avoid, but the enemy will mostly stay confined to that area. These are:
- Sector A – Berserker
- Sector B – Big Grunt
- Sector C – Hard Grunt
Tip: You don’t need to return to the gymnasium between sectors. There’s a tunnel system at the back of the map that lets you move between sectors much faster and more safely.

Escaping the trial
Once you’ve collected all three keys, return to the gymnasium and use them on the three electronic locks. After this, Coyle will be deployed from the door in the top-right corner of the gymnasium. The gate you originally entered the gymnasium through will open, so this is your cue to run before Coyle catches you.
Make your way to the Shuttle and escape to complete the trial.
Best Rig for Cancel the Autopsy
There’s no Rig that’s particularly over-powered on Cancel the Autopsy, so I’d run whatever rig you are most comfortable with. Since it’s a pretty short and simple trial, I typically use the Stun rig in case I run into any enemies unexpectedly in the three sectors.
