Navigating the challenges of Mortal Kombat 1 Invasion Mode? Discover how to unlock the ‘Another Test Subject’ Klue and access unique rewards in Shang Tsung’s Laboratory.
Players encounter various challenges in Mortal Kombat 1’s thrilling Invasion Mode, including cryptic Klues guarding valuable rewards. ‘Another Test Subject’ stands as one such enigmatic Klue situated in Shang Tsung’s Laboratory. To seize the coveted treasure—a skin for General Shao—players must overcome this unique challenge. In this guide, we unveil the secrets to completing ‘Another Test Subject’ and claiming your well-earned chest.
Exploring the Perplexing Frisky Level:

As players venture through the Invasion levels of Mortal Kombat 1, they’ll encounter a multitude of Klues that conceal hidden treasures. Shang Tsung’s Laboratory harbors two of these enigmatic Klues. The one in question is nestled within the level called “Frisky,” where players engage in a fierce battle against Kitana. The Klue that must be deciphered to conquer this level is aptly named “Another Test Subject,” paying homage to one of Shang Tsung’s infamous Fatalities.
Completing ‘Frisky’ with ‘Another Test Subject’ in Mortal Kombat 1:

To overcome the Frisky level and unveil the treasure it guards, you must play as Shang Tsung, as any other character will prove ineffective. Victory against Kitana is achieved by defeating her once during the match. However, the crucial step in unlocking the chest is executing Shang Tsung’s close-range Fatality sequence:
- Back
- Down
- Down
- Facebreaker
The Facebreaker command varies depending on the platform:
- For PlayStation: Square
- For Nintendo Switch: Y
- For Xbox: X
This Fatality showcases Shang Tsung seizing his opponent with claw-like hands and administering a brutal molten demise. While some may suggest using any of Shang Tsung’s Fatalities, it appears that the second Fatality is the most reliable for this challenge.

Upon successfully executing the Fatality, the obstructing obstacles will be removed, allowing you to access the treasure chest. Inside, you’ll find the ‘Naked Ambition’ skin for General Shao, a valuable addition to your collection as you journey through Shang Tsung’s Laboratory.
