After unlocking Shang Tsung, you should perform his second Fatality at the end of the Klue space match. 

The button mapping to Second Fatality looks like this:

Back -> Down -> Down -> Facebreaker

The Facebreaker button in Mortal Kombat 1 varies depending on the platform you’re playing on. On PlayStation, it’s executed by pressing Square; on Switch, it’s Y, and on Xbox, it’s X. 

In the Fatality, Shang Tsung grasps his opponent with his claws and feeds them what appears to be lava, causing them to melt away. Although some players have suggested that any of Shang Tsung’s MK1 Fatalities might work, it typically requires his second Fatality to trigger the Another Test Subject Klue in MK1.


After successfully performing Shang Tsung’s Fatality in Mortal Kombat 1, the obstacles blocking the path to the treasure chest will be removed. Players can then obtain the Naked Ambition skin for General Shao and proceed further in the lab.

That’s how you can easily solve the MK1 Another Test Subject Klue. Get the Netherstone for the ability to unlock the Nethergates, which are hidden portals to the Nether realm in Mortal Kombat 1.
