To get the Enough Already achievement/trophy in Mortal Kombat 11, you need to explore the Krypt mode.
The Krypt Mode is where you travel Shang Tsung’s island as a nameless warrior, and collecting different treasure. The treasure contains a variety of things, like character moves or artwork.
To get Enough Already, you need to hit the gong in Krypt mode. The gong is in The Courtyard section of Shang Tsung’s island. The Courtyard is the section beyond the wooden gates at the Palace Entrance, the first area you begin.
You’ll need Shao Kahn’s hammer, which is fortunately at the Palace Entrance. The hammer is sitting on podium at these coordinates – (4475, 231).
With the hammer, you can break the wooden gates at (3210, 190), and enter The Courtyard.
There’s a breakable wall at (969, 3791); break it with the hammer. Beyond the wall is where the gong lies.
Specifically, the coordinates for the gong should be around (-2948, 240), though the gong is easily spotted after you destroy the wall.
Walk up to the gong, and it hit it with Kahn’s hammer. Not only will hitting the gong give you the Enough Already achievement/trophy, but it will also open the gates at (-2948, 240).
