There is a difference between what triggers an unlock and what people assume triggers it. How to Unlock Fatalities in Mortal Kombat 1 is a good example of that gap.

Most advice on this topic assumes you already know half the answer, which is exactly the problem. Start with the simplest option before touching anything that is hard to reverse. It helps to know why a step exists, because then you can adapt it when your situation differs slightly.

The short answer

Meet the requirement once, in one session if possible — partial progress is where people get confused about whether it worked.

What the requirement actually is

If something here stops matching what you see on screen, the game has probably changed a value in an update. If you are short on time, the first section alone is usually enough.

The quickest way to meet it

Most advice on this topic assumes you already know half the answer, which is exactly the problem. If something here stops matching what you see on screen, the game has probably changed a value in an update. There is a fast way and a safe way, and they are not the same thing.

  • Write down what you changed, so you can undo it if the result gets worse.
  • Back up your save if the game gives you the option.
  • Check the version you are running before following any step-by-step advice.
  • Test one change at a time instead of five at once.
  • Keep a spare loadout for the attempts that go badly.
  • Confirm you are on a save where the requirement can still trigger.

How to tell it worked

The community figured most of this out through repetition, and the pattern has held up well. Most advice on this topic assumes you already know half the answer, which is exactly the problem. If the item is account-wide, you only need to do this once ever. The confirmation is easy to miss if it appears during a loading screen.

Treat the numbers as a guideline; your exact result depends on your setup and current version. If something here stops matching what you see on screen, the game has probably changed a value in an update. Unlocks that depend on a hidden counter are the ones that generate the most bad advice.

Mistakes worth avoiding

  • Following a guide written for an older version and assuming nothing moved.
  • Skipping the preparation step because it looks boring, then repeating the hard part four times.
  • Changing several settings at once, then having no idea which one helped.
  • Trusting a video thumbnail over the actual patch notes.
