Mortal Kombat 1: Another Test Subject Klue Solution

Shang Tsung's Laboratory has one of the most confusing klues in MK1 Invasions. Here's how to get Another Test Subject.

Mortal Kombat 1 continues the franchise’s long history of having secrets and unlockables. While there are some when it comes to stages and characters, the Invasions mode has plenty of unique ones itself. Unfortunately, one of them might not be something that every player can complete. Here’s how to solve Another Test Subject in MK1.

The solution for the Another Test Subject klue and secret objective is to play the associated match as Shang Tsung and finish your opponent with his second fatality. Make sure not to accidentally cause a Brutality and defeat the opponent like normal. For reference, the input for this unique finisher is as follows:

  • Shang Tsung’s Second Fatality — Back, Forward, Back, Triangle/Y

What if You Don’t Own Shang Tsung?

Unfortunately, you need to use Shang Tsung for the Another Test Subject klue, and specifically end the match with his second fatality. There are no alternative solutions for completing the objective. If you don’t have him unlocked, you’ll never get to solve this and access the rewards.

The good news is that none of the rewards are too outrageous. Three legendary talismans are pretty nice but might not mean much to players trying to grind through the mode fast. Aside from some legendary glasses for Johnny Cage, the only other notable item is a palette for Shao Khan. That latter palette can be bought from the Seasonal Items store, though. Unless you want to unlock every item or want to kustomize your MK1 characters for cheap, this exclusive challenge can be okay to skip.

How to Unlock Shang Tsung

Shang Tsung is a premium character that was initially offered as a pre-order bonus for any edition of Mortal Kombat 1, but can now be purchased from your platform’s respective store. As a separate DLC, he costs $7.99.

That’s how to solve the Another Test Subject klue in Mortal Kombat 1. If you had similar troubles on the Tarkatan Colony Map, we also have a guide for the Flipping Out klue. All other tips and tricks can be found on our MK1 guides page.
