This walkthrough is for Zero Escape The Nonary Games: 999 Knife Ending. Please take note that the walkthrough contains spoilers.
The Knife ending is one of the Bad Endings in the game. It is actually the first Ending that I’ve gotten. It’s very straightforward if you just follow the Flow Chart below.
Flow Chart
There are various ways to get the Knife Ending. The key point is to ensure that you mix the white and red keys in the flow chart and choose Door 6 at the last Checkpoint.
Note: If you chose to go through the red route (Door 5 and then Door 8), you will need to make sure that you fail at least one of the criteria (red key to show locked) so that you will get the Knife Ending.
Room Route:
- Start: 3rd Class Cabin
- Door 4: 2nd Class Cabin and Kitchen
- Door 5: 1st Class Cabin and Casino
- Door 7: Operating Room
- Door 8: Laboratory
- Door 6: Steam Engine and Cargo Room
